Issues with logic apps webhooks limit while connecting to Microsoft Bookings

We have created Azure Logic Apps webhooks to fetch appointment data from Microsoft Bookings portal, but we are getting the below error in our Logic Apps:

Status Code: 429

Status(StatusCode=\"ResourceExhausted\", Detail=\"Only 5 webhooks allowed per bookings business\")

This is known limitation from Microsoft:

1. Only 5 flows can be created per Bookings Mailbox. Description: For a Booking Mailbox, only 5 flows can be created. This is a Bookings Mailbox level limit and not a per admin limit. If you are looking for more than one action for an appointment trigger, you can add that in one of the existing flows by using the Add Action button. You can contact other Booking administrators for support.

We are unable to delete existing webhooks for the particular Bookings mailbox. Please guide me how I can get the webhooks details and delete the unused one?
