Total number of Users who have access to a Sharepoint document

All,

I am a new Modern Sharepoint Online Site Owner

I need to find out the total number of Users that have access to a document on a Modern Sharepoint Online Site.

Looking at the Manage Access, I see and the following icon:

I understand I can select Advanced and manually count the Users that have access.

But isn't there a Powershell command or something I can run to get the total number of Users that have access to a document?

Any assistance would greatly be appreciated.

T.J.
