I need full SDK implementation for Instant Games.
What I need to achieve is to send update(or share) in messenger with a payload.
Users that click on that link will start the game in that context.
Something like multiplayer in turns. Many games have that feature
The full Instant Games SDK has a wide range of features including some that would be major projects and have questionable utility to Construct users, such as the Bots framework. We'd rather deal with suggestions for specific Instant Games features, e.g. as posted at https://construct3.ideas.aha.io/ideas/C3-I-486, so we'll close this suggestion and follow up there.
