issue in completing challenge under Data security (Defining Sharing Rules) I have done all things ,like making Organization-Wide Defaults as Private and creating a group for rule Training coordinator and providing readonly access for Project data based on priority. but still getting error as "The sharing rule did not behave as expected. "

Hi Experts,
I am trying to solve this challenge but not able to solve because of salesfore license issue. Salesforce only allows 2 'Salesfoce' license for DE. Is there a way to solve this challenge? Please help.

Create a Profile and Permission Set to properly handle field access
The Marketing Coordinator and Account Manager both require access to view and update Account Records, but only the Account Manager should be able to see and edit certain fields. Specifically, only the Account Manager should be able to see and edit the Rating field. The Marketing Coordinator should not be able to see or edit the Rating field. Create one profile and one permission set with the appropriate field-level security to solve for this use case.The profile must be named 'Basic Account User' and result in an API name of 'Basic_Account_User'. It should use the 'Salesforce' user license type.
The permission set must be named ‘Account Rating’ and result in an API name of 'Account_Rating'.
