Some variety of a pin spanner if you google what those look like. There are frequently adjustable ones.
I’ve managed to open freewheels and other things like this by using a small punch or anything with a small point that can catch in the little hole, and a little hammering, and a little patience.

There is likely a socket with four pins that is used, but as mentioned a pin spanner or even a punch could likely do the job.

I did tried with a hammer and punch tool, but didn’t work. I sent an email tot the manufacturer. Hope they will help.
I will also try heating it and then use the punching technique.

Maybe something like [this](https://www.parktool.com/en-us/product/pin-spanner-red-spa-2)?
I used something like [THIS](https://images.app.goo.gl/D8u4RBgQsp7oF24X8). But it bent my wrench.
Initialy I thought I pushed in the wrong direction, but I tried both ways and it didn’t move.
Mybe these little f*ckers are not ment to be serviced.
