Bluetooth with Ubuntu

I have a LattePanda Sigma with two SSDs. One runs Windows 11, the other Ubuntu. With Windows, I use a Logitech bluetooth keyboard and a Logitech bluetooth mouse. I use a small numeric keypad to control Grub.

I would like to use the bluetooth keyboard and mouse with Ubuntu, but I have been unsuccessful. In the GUI I don’t find a bluetooth page in settings. In the terminal it all seems to be about a MAC address.

How can I do this? Thanks, Jim
