Need replacement rubber feet for GPD Win Max 2

One of the rubber feet on my WM2 fell off. It seems to have swelled, got too big for the recess that it was in, and popped out.

I tried to put it in but it keeps coming back out and the adhesive isn't holding it on anymore.

Now the laptop doesn't sit flush on a table and that corner with the missing foot rocks down when typing or moving it.

Can I buy replacement rubber feet for it?
