Can't attach EULA to DMG in Big Sur

[Aleksid1]

hditul flatten/unflatten verbs are deprecated and removed in macOS Big Sur. So it's not possible to attach EULA to a DMG in Big Sur. I saw alternative solution here:
developer.apple.com/forums/thread/668084

Please fix it.

@Aleksid1 you've managed to use the method in the link?

[Aleksid1]

No, I couldn't. I've understood an idea with hdiutil udifrez , but I couldn't find complete files with examples: my-eula.plist.template and my-eula.plist

Reading at the post, you should extract that PLIST using:

hdiutil udifderez -xml <YOUR_DMG_PATH>

Then introduce your EULA content there.

It's a little tricky because you have mixed steps in the main post and in an answer:

I'm willing to bring this fix to create-dmg. Thanks for the tip @Aleksid1.

Thanks for your advice! Regrettably I still can't perform these steps correctly.
I would grateful for your help with modifiying the script. I can check it and inform you about a result. I have 2 Macs with Big Sur - Intel and M1.

You can already test it: f75cc03

Just clone the repository and check it out.

Thank you very much! License was attached to a DMG correctly.
I tested on Macbook Air M1 / macOS 11.1 Big Sur
