I use the Keyboard paired with an Logibolt dongle and the dongle it is connected to an iMac 27" model from 2017, and I think it is an recent issue because i can't use this keyboard ar the start of my computer holding the key to enter in boot selection (it is not working anymore, i need to connect a wired keyboard or the original apple's keyboard to enter in the boot selection for the OS. I have mx keys mini and a mouse Master 3 s both connected with a logibolt dongle to my imac.
