Guest inviter and application developers are not considered administrator roles.
To download a list of users
Sign in to your Azure AD organization with a User administrator account in the organization. (External link here.)
Navigate to Azure Active Directory > Users. Then select the users you wish to include in the download by ticking the box in the left column next to each user. Note: At this time, there is no way to select all users for export. Each one must be individually selected.
In Azure AD, select Users > Download users.

You can see the status of your pending bulk requests in the Bulk operation results page.
