Description of the problem, including code/CLI snippet

I am trying to "guess" what would be format of --positiion POSITION syntax for CLI. My one of attempts

gitlab -o yaml project-merge-request-discussion create --project-id 14907 --mr-iid 35 --body ccc --position base_sha=eeb82032ed67cdff723a135890770e064871fafe --position head_sha=db02d7af62dc2fc64fde3ea7840284ab24445cd6

Expected Behavior

Documentation would list some more advanced examples.

Actual Behavior

Documentation listed only basic usage

Error I am getting:
Impossible to create object (400: position is invalid, position[base_sha] is missing, position[base_sha] is invalid, position[start_sha] is missing, position[start_sha] is invalid, position[head_sha] is missing, position[head_sha] is invalid, position[position_type] is missing, position[position_type] is invalid)
