LeeJinWoo - We tried below steps of adding and removing participants using PATCH api and we are getting correct participants list as follows:
1.Creating an online meeting with participants A & B.

POST https://graph.microsoft.com/v1.0/users/cxxdef33-d7xx-444c-xx28-be1f95e6b6f2/onlineMeetings

{
    "startDateTime": "2023-12-29T14:30:34.2444915-07:00",
    "endDateTime": "2023-12-29T15:00:34.2464912-07:00",
    "subject": "User count Meeting",
    "participants": {
        "attendees": [
            {
                "upn": "admin@M365x17798679.onmicrosoft.com",
                "identity": {
                    "user": {
                        "id": "ce9def33-d7fc-444c-8728-be1f95e6b6f2"
                    }
                }
            },
            {
                "upn": "adelev@M365x17798679.onmicrosoft.com",
                "identity": {
                    "user": {
                        "id": "75f9fd6b-bebd-4039-b576-2c7c87b1f5b1"
                    }
                }
            }
        ]
    }
}

 

In result we have 2 participants

 

2. Then added another participant C to the existing meeting using PATCH function.

PATCH https://graph.microsoft.com/v1.0/users/cxxdef33-d7xx-444c-xx28-be1f95e6b6f2/onlineMeetings/{meeting-id)

{
    "startDateTime": "2023-12-29T14:30:34.2444915-07:00",
    "endDateTime": "2023-12-29T15:00:34.2464912-07:00",
    "subject": "User count Meeting",
    "participants": {
        "attendees": [
            {
                "upn": "admin@M365x17798679.onmicrosoft.com",
                "identity": {
                    "user": {
                        "id": "ce9def33-d7fc-444c-8728-be1f95e6b6f2"
                    }
                }
            },
            {
                "upn": "adelev@M365x17798679.onmicrosoft.com",
                "identity": {
                    "user": {
                        "id": "75f9fd6b-bebd-4039-b576-2c7c87b1f5b1"
                    }
                }
            },
            {
                "upn": "alexw@M365x17798679.onmicrosoft.com",
                "identity": {
                    "user": {
                        "id": "1dd50ba7-e5bd-46ea-b34e-80a415148de7"
                    }
                }
            }
        ]
    }
}

 

In result we have 3 participants

 

3. Then removed added participant C using PATCH function.

PATCH https://graph.microsoft.com/v1.0/users/cxxdef33-d7xx-444c-xx28-be1f95e6b6f2/onlineMeetings/{meeting-id}

{
    "startDateTime": "2023-12-29T14:30:34.2444915-07:00",
    "endDateTime": "2023-12-29T15:00:34.2464912-07:00",
    "subject": "User count Meeting",
    "participants": {
        "attendees": [
            {
                "upn": "admin@M365x17798679.onmicrosoft.com",
                "identity": {
                    "user": {
                        "id": "ce9def33-d7fc-444c-8728-be1f95e6b6f2"
                    }
                }
            },
            {
                "upn": "adelev@M365x17798679.onmicrosoft.com",
                "identity": {
                    "user": {
                        "id": "75f9fd6b-bebd-4039-b576-2c7c87b1f5b1"
                    }
                }
            }
        ]
    }
}
 
In result we have 2 participants as expected.

Hi, Happy New Year.
In your third step guide, remove the last C user from the chat window of the meeting, not the API, and then GET the meeting information through the API.
In this case, user C still exists in the participant list.

    LeeJinWoo - We tried removing the participant manually and again ran the GET query using the meeting Id and can observe that its returning 3 participants.
    This seems to be by design because the removed participant was part of the meeting and using that meeting id only, we are getting meeting details. So, its showing 3 participants.
