Unale to connect using the MongoDB shell

Hey, I am unable to connect to my sample cluster, Sandbox using mongosh. I have tried troubleshooting using the documentation but I seem to be getting the same errors. Can someone help me out?

Post a screenshot of what you are doing and shows the issue you are having.

resolved it, thank you!

I had to type in just the connection string, but I was entering the whole command given on the instructions!
