Hello Dave Degrace,
Thanks for your question.
If you are an admin, you can navigate to entra and select "Users" to see a list of all users in your directory. You can also go to "Roles and administrators" to see the roles assigned to different users, such as Global Administrator or other admin roles that can give you a clue.
But without detailed knowledge of your organization, your best bet is generally to find another admin to grant you access.
You can mark it 'Accept Answer' and 'Upvote' if this helped you
