Im getting error when connecting the cluster to my shell

I’m getting an error when connecting the cluster to my shell. in video, there are using connect via mongo shell but in my cluster, there is an only option connect via string. I tried it but I’m getting an error that connection has failed.

i’m getting this error,
C:\Users\Cloude Labs>mongo mongo “mongodb+srv://” --username basha97
MongoDB shell version v4.0.7
Enter password:
connecting to: mongodb://
2019-05-04T13:28:13.558+0530 E QUERY [js] Error: Authentication failed. :
exception: connect failed

It says authentication failed
Please check if you have supplied correct id/pwd

Also you typed or cut & pasted mongo twice in your command above
This also could be the reason for connect failure
