Join via Profile Process

How does one enable players to join my game via my Profile. Everyone keeps saying they can’t join via my profile.

I have put the most possible restriction access on my Xbox settings by design. Then I have enabled settings so people can see my profile.

In game, I went to the Network & Social, and set the Group Privacy to Open to Public.

So when I make a post in the Achievements section, people are able to see my game posts but they still can’t join via my profile. What am I missing?

Some of the privacy settings will prevent random individuals from seeing your open game or joining it, so you might want to review all the options carefully. The easiest way to have people join your game is to have them on your Friends list.
