command failed: MongoError: CMD_NOT_ALLOWED: profile

Question

I am using the Atlas free cluster mongodb and try to enable the profiler for the monitoring purpose and I have an Atlas Admin access on the cluster

On the setting, the profiler option is enabled as in the diagram above

While I am running the command db.setProfilingLevel(2) getting the below error:

MongoDB Enterprise Cluster0-shard-0:PRIMARY> db.setProfilingLevel(2)

Mongodb Atlas free tier blocks profiling options.

You can find operations that are not permitted in Mongodb Atlas free tier below
