Instant milk frother not working, how to open and repair it?

Dear IFIXIT community,

My Instant milk frother stopped working and I would like to repair it.

The first hurdle is that there are some deep proprietary screws that I can't reach with my IFIXIT Pro toolkit. See attached photos. Any suggestions?

Once I am able to open it, I may need further help. I am new to fixing things, but I like the idea very much. Thank you for your support.

Marco
