Prompt to accept integration manager polices on use

[manuroe]

Before you:

• add a widget to a room
• use the sticker picker
• (TODO: Check if we need that on mobile) allow a widget to load for you in a room
  • This does sort of work already with ToS for ISes/IMs: prompt on use screen matrix-org/matrix-react-sdk#3199, but the UX is such that your are prompted when entering a room with a widget, not when allowing it to display
  • Time of prompting for existing widgets fixed by Defer IM token until widget is shown and permission granted matrix-org/matrix-react-sdk#3240

You must read and agree to the policy documents provided by the integration manager.
