Connection Kobo to new Macbook Pro

Hi everyone,

I just bought a new MacBook Pro which doesn't have any USB ports anymore, so you would have to use a connecting piece. However, I can't seem to be able to connect my Kobo to my laptop anymore. It doesn't show on the desktop, nor via the Kobo app, I have tried all ports on the connecting piece and different cables, but none of it seems to work.
Do you have any other ideas?

Many thanks!
