What wordpress username role does the service providers have to be in order to click on the client?

I receive this message when I click on the client from here:

Appointments+

My Appointments as Provider

My Appointments

Service Client Date and time Status

You do not have permission to edit this user.

The service provider is currently set to “Subscriber” role.

I tried setting the role to “editor” but got the same error.

I’m hoping they do not need administrator role in order for them to look at the clients info.

Thanks!
