Why share in Inbox is not working in FB Instant Game

Phaser 3
1

I’m developing a FB Instant Game using Phaser 3.18. I want to share the game to the inbox of any friend,no matter from web or from mobile/messenger. I’ve tried -

this.facebook.openShare(...);
this.facebook.openInvite(...);
this.facebook.openChallenge(...);
this.facebook.openRequest(...);

But I didn’t get the expected result. When I’m from web, it’s giving option to share in profile, when I’m from messenger, it’s giving option to share in inbox. But how I can send it to inbox always?

Thanks in advance for your time :slight_smile:
