Command 'mongo' not found, did you mean: command 'mono' from deb mono-runtime (6.8.0.105+dfsg-3.2)

I successfully installed mongodb from the given instructions on this site server also started successfully with the response :

● mongod.service - MongoDB Database Server
     Loaded: loaded (/lib/systemd/system/mongod.service; enabled; vendor preset>
     Active: active (running) since Mon 2022-09-26 14:23:31 IST; 1min 59s ago

     CGroup: /system.slice/mongod.service
             └─2155 /usr/bin/mongod --config /etc/mongod.conf

Then I’m tryomg to open mongo shell with the command ‘mongo’ but it showing:

Command 'mongo' not found, did you mean:
  command 'mono' from deb mono-runtime (6.8.0.105+dfsg-3.2)
Try: sudo apt install <deb name>

Why? I searched a lot for this but I didn’t get the solution please help.
