(Bedrock) Changing Gamemode in chat

In the chat section of bedrock edition you can a lot of things but more need to be available under the / button. 

A Feature that could be added for chat in 1.14:

Gamemode: Gamemode should be available under the / button. 

When you tap the / button Gamemode should be under set world spawn. When gamemode is clicked 3 other buttons should pop up that survival, creative and adventure. When one of those clicked they will change your personal gamemode ( unless your the host and go in settings and change the world's Gamemode). Anybody that has cheats activated can simply change their personal gamemode in chat. 

This should be in 1.14 to make it easier to change your Gamemode. It will also help with chat features, map makers, and to add on to the 1.14 Update.
