mySIMBL not working on apple silicon

[Endermen359872]

Hi dear developers!
Recently I upgraded my mac from intel chip to apple silicon chip and I found it not working well on it.
Firstly, as I launch mySIMBL , a blank window pop out and I have no idea about it. The button on the right is install however I have no idea what it is. Password is required after clicking install button showing "mySIMBL want to make changes" . Each time I launch the software it will show me the blank window and it seems nothing happened after clicking the install button.

Secondly, I install some plugins in it (Afloat and AfloatX) and the plugins didn't work at all. However they made the window of mySIMBL itself keep afloat. Weird isn't it?
Thirdly I found close buttons on the top left corner are not in the correct position.

I haven't met these problems when I use it in intel chip mac.
Since English is not my first language, mistakes are difficult to avoid. Hope you can understand my feedback correctly.
Hope these problems would be solved soon.
Sincerely
