Question about Unified Push

[bahur142]

Hello developers of Schildi Chat.
Sorry for opening ticket in your issue tracker, but I don't know where to ask a question about UP. Feel free to close it.

I've managed to do my own fork of Element Android about an year ago. Using also self-hosted push server Sygnal for delivering pushes. Last days I am reading some publications about Unified Push and looking forward on how can I use it.
Since Element still not provide UP, I am looking at your application Schildi Chat and see that you have implemented successfully UP. Since I am not a programmer and did not understand Java/Kotlin (though I have my own fork), want to ask about the following commit:
a3a946f#diff-44923f4e9b5a6e14764ee8b524a9d8afaeb48ac8f6cb8d708b0794965c557692
If I use the code of these 24 changed files at the time of commit, can I build successfully a version of my own Element with UP support? Is it enough to support UP only with this commit and the files changed?

For building Element with unified push, easiest would be just using this PR: element-hq#3448
SchildiChat's UP implementation is also based on that PR.
