how to downgrade photoshop 2021 22.1.1 to 22.1.0 ?

Hi, I have some problem.

I need to use photoshop 2021 version under 22.1.0 .

But I cannot find "previous version" in CC app.

I tried to follow the guide, but the version of CC may not match.

There's no "previous" or "another" version button.

So, how I downgrade my photoshop 2021 22.1.1 to 22.1.0 or 22.0.0 or 22.0.1 ?

Please help me.
