Users Add-on & BuddyPress Xprofile Fields

I just purchased the “Users Add-on” and I need it to work with BuddyPress Xprofile fields. I thought I could to this because I saw the “Add meta” options — but it does not work. I saw a support post about this that said:

“What you can’t do is integrate Caldera Forms with BuddyPress directly, for example to add data to an xProfile. To do this you need run action to do a custom process with the submission.”

I’m not sure what this means… Is there any direction on how I can do this? Thanks in advance!
