Clarify how matomo user roles displayed during wordpress user creation should be used

[diosmosis]

When creating a user a role must be specified:

The possible roles include:

• Matomo Super User
• Matomo Admin
• Matomo Write
• Matomo View

but the only role that allows viewing the Wordpress admin page, and thus the Matomo Analytics admin pages, is Administrator.

It seems likely that a new user to Matomo for WP would create a new user with one of the above roles, then be confused as to why they can't access the wordpress admin page.

Why these roles exist and how they should be used should be clarified.
