Connecting a BBQ grill

At the recent show in the NEC we saw a range of Camping Gaz desk-top grills which looked interesting.  However, are these, designed to work with Camping Gaz and other butane cylinders going to be compatable with a 2021 Broadway?
Also, are there any other attachements we'll need to get to connect up any similar product?
Grateful for any advice

Campinggaz table top Party Grill is available in 2 models to work with disposable cylinders or to refillable cylinders .

That link has what looks like two different versions. One version seems to have a cylinder screwed directly to the burner - ie high pressure and the other has a hose and regulator. Only the latter could be plugged into the van's external gas tap, surely.
