How to Write a Script to Implement Changing Corners' "Rounding" to "Relative"

I only know a bit of JavaScript and have tried to implement changing Corners' Rounding to Relative with the help of ChatGPT, but I can't get it to work.

I need to use it very often, and each time I have to tediously double-click and then click Relative, or tediously click in a far away toolbar.

The effect I'm trying to achieve in ChatGPT is to change to Relative when there are more than 2 anchors selected, when the angle is less than 90 degrees, and when Rounding is Absolute.
