Change Default PackerPolicy

I wanted to change DefaultPackerPolicy for my game. I found sample code here;

The value I wanted to change is entry.settings.compressionQuality

I have to pass some integer to this. I can’t find any information on what this value is or how to change it.
Can anyone provide some help on this?

Shows a similar quality value. I would assume they are using this. If you are creating your own editor script using the example in your provided link, I think you could use normal editor mechanics to add a slider to change between 0 and 100, then apply that slider value to your quality, instead of the ins value.
