Or you can perform an advanced search for the macro name (see below), which will give you a general idea of how many pages it has been used on. This will not consider pages you can’t see or if the app is used multiple times on a page.
Here is another process provided by Atlassian to search the usage of macros via API; refer to the below documents:

To use the API search function, you must add the below search after your instance URL. The first will give you all pages with the HTML macro up to the 1st 25 uses. The second raises the limit to 250.
