Is your feature request related to a problem? Please describe.
While playing with just a controller it would simply be impossible to type anything in chat, or anywhere in general. Signs, Book and Quills, Using commands.

Describe the solution you'd like
When you interact with a text box such as chat or a sign, a small on-screen keyboard appears that you can navigate with your controller. pressing down the interaction key would register a keystroke and simply write on the chat box. Pressing a new keybind for deleting text would simply register the key backspace. And anıother keybind for enter, etc, etc.

Describe alternatives you've considered
Theres no alternatives comes to my mind.

Additional context
It could be a lot to add but there can be a autocomplete feature for keywords like when you press di- autocomplete shows "dirt, diamond, dig", etc. this could be configured for language support.

could we get an option to disable this? i switch to keyboard to type messages so the popup keyboard is extremely annoying.
