Have you tried restarting your M1 Mac, just in case?
I've heard from M1 Mac users who can use Bangle.js just fine, so it's not that the M1 can't do it.
HOWEVER something came up a few months ago with a new version of Mac OS that could be the issue. If when you first installed Chrome and it asked if it could have Bluetooth permissions (which could have been months ago!) you said 'No', Chrome won't be able to access Bluetooth devices, and I'm not sure Chrome even knows this is the case - it just doesn't see any devices. You'll need to go into the Mac OS permissions and choose to allow chrome to access Bluetooth before it'll work
