Comments from Submitter:
I got the 42131 set from the Lego online store on July 2, 2022 (delivery date). It came with the bb1277c01 hub (with 4 screws on the bottom). The bricklink inventory currently says it comes with the bb0961c01 hub ("clip opening" hub). Therefore I am adding bb1277c01 as an alternative part.
NOTE: I have never seen the bb0961c01 "clip opening" hub, and I found no images of the back of the "clip opening" hub on bricklink or elsewhere, so I am not 100% sure if/how the two hubs are different. However, I am 100% sure that the hub we got in my 42131 set has 4 screws that must be removed to change the batteries, and looks identical to all the images of bb1277c01 ("screw opening" hub).
