Welcome to the forum, Pam.
I can confirm that patience is a key here. It took my colony a few weeks to take on the FH2+ frames while they were still busy making their new home liveable . The video Eva has linked has some tips, but as a new beekeeper I didn’t have wax to lure them into the FH frames, so I just waited and watched what they’ll do.
After a while you might be able to see them work on the center frames first and start closing the bridges in the lower cells with wax. I have just posted a picture on what that looks through one of my side windows:
I am not expecting a big harvest in my first year anyway, but I am learning a lot. And if I only get a few drops of honey, I am happy with that too.
