Passing user data to Intercom

Hi, I want to add Intercom to my app, can someone explain to me, how can I make it avaliable for only logged in users and pass their data to Intercom.

Sincerely.

Check available plugins, you may find what you need

They only makes the connections, I am already using them and there r no more settings on them. Like show chat only to logged in etc

This one for example:

Have something for logged in user. After, you need probably to just show element on the page if current user is logged in. (look at this demo page editor: Nocodeventure-plugins | Bubble Editor and check what they do for “Activate chat for logged in Users” button)

I really dont want to pay for that.

seems like I can pass those user.* variables w cooikes, anyone knows how can I do it?
