Currently, we have an option of viewing users under the Administration tab by filtering a specific product. However, it's not possible to filter specifically by the "User" role. In the current filter we have the following options:
Filter by:

• Organization Admin
• Site Admin
• User Access Admin
• App Admin
• Confluence Guest

The suggestion is to add the "User" option in the filter options.

Workaround

The only workaround is to to export the users's list and filter the data in the Excel after it is downloaded.
