MongoDB Atlas CMD_NOT_ALLOWED: grantRolesToUser and dropDatabase Permissions Issue

I am encountering issues with MongoDB Atlas permissions while trying to manage user roles and perform administrative actions. Specifically, I am facing the following errors:

MongoServerError[AtlasError]: CMD_NOT_ALLOWED: grantRolesToUserMongoServerError[AtlasError]: user is not allowed to do action [dropDatabase] on [test]

Problem: When attempting to use the grantRolesToUser command in MongoDB Atlas, I receive a CMD_NOT_ALLOWED error. Similarly, I am unable to execute dropDatabase due to permission restrictions.

Context: I am using MongoDB Atlas as my managed database service. I have administrative privileges in the Atlas project but seem to be restricted from executing these commands.

Permissions Granted: I have granted readWrite privileges for the user in MongoDB Atlas, specifically on certain databases.

Steps Taken:

I have verified that my user account has administrative roles within the Atlas project.I attempted to modify user roles and permissions through both MongoDB shell (mongo) and MongoDB Atlas dashboard (https://cloud.mongodb.com), but encountered the same permission issues.

Expected Outcome:

I expect to be able to manage user roles (grantRolesToUser) and perform administrative actions like dropDatabase without encountering permission errors.
