Update & additional questions on post: Shimano Altus cassette tool and compatible replacement cassette
Solved! Thanks a lot for the great support Redditors!
Update one previous post:

After some delays I tried to remove to old freewheel. Since my tool didn’t fit over the nut of the axis, I removed it including parts of the ball bearing.
The tool seems to fit properly, but even with almost unreasonable (at least in my inexperienced opinion) force I can’t unscrew the freewheel.
I tried to turn counterclockwise, didn’t work.
I cleaned with isopropanol and afterwards used WD40 to break up potential rust. Didn’t work.
I used a torch to heat it up (carefully, at least as careful as you can be with a torch), didn’t work.
I used a hammer in the direction of the axis to break open any potential rust (also with reasonable force), didn’t work.
Then, after an uneducated guess of a third party I tried to turn clockwise even if I thought it was not logical, didn’t work.
Now I’m out of ideas how to remove the freewheel.
Hence I have two questions:
I used a video of parktool recommended in my first post to identify the correct tool.
Can anybody confirm that the tool is correct or if another tool is requires?
There are two small holes (red arrows) that could be a possibility and also some notches (green arrow) some ring close to the smallest sprocket, please see pictures.
Does anybody have a recommendation how to remove the freewheel without destroying anything in this situation? (The bike is a daily driver, so if I would break the wheel that would be a real issue (on top of the trial to minimise investments into this bike…)
I’d be very thankful for your further support on this, I’m really out of ideas…
Additional info: after cleaning it was possible to read the brand and some other info on the freewheel:
