co-op screen mode to allow players to see the perspective of other players

Bedrock/Java editions should have a Co-op screen mode that would allow players to see other players perspectives. ( I am thinking something like the "map in off hand" kind of scale/placement. )

Likely requiring players to "request/approve" access to "look over your shoulder".

It would be useful to help players learn what others are doing in real time and could be helpful for finding each other and coordinating mob fights/raids.
