I had this issue before and now again with the early access. I'm from Austria and I use the German QWERTZ layout but it doesn't really seam like the 1Password App knows or adapts to it. When I check I currently can only see one shortcut and it is CTRL + SHIFT + \ to Open 1Password but even that one shortcut is already "useless" on a QWERTZ layout (for the \ key you also need to press ALT GR).
I don't know what the best solution would be but I'd love to use shortcuts without manually adjusting them first (which isn't possible in the early access either, though I guess it will be in the future eventually). Other programs manage to just "detect" what the key would be on the same spot (though even then I wouldn't recommend \ because there are layouts that don't even have that key spot at all).
This would also be nice for the Linux app of course
