Airtable collection and user collection cannot have a relationship?

I was reading on the slack group that a user said an external collection on Airtable and a user collection (adalo) cannot have any type of relation… Is this true (I don’t want to spend $50 just to find out)

So if I were to create a super simple app - lets say a list of all restaurants in my city, and that list was an external collection on Airtable… There would be no way to have a “like” type button for users to save their favorite restaurants because the Users (native) DB and the Restaurant DB (Airtable) can’t communicate in any way?

Is there any type of work around at all?

Scrap that… Just found the video showing how to do it
