I mean the commit message. Now your commit message's ChangeLog only
mentions updating webrtc-for-telegram-desktop. See my last telegram
commit 6192acf8b77 for an example of what I'm talking about.

I would assume the ChangeLog file is autogenerated based on the commit
messages.

You would probably have to patch the `CMakeLists.txt` so it doesn't try
to build libsrtp from source, see what I did with crc32c in the
mentioned commit for reference. It is quite possible that telegram
doesn't actually need the source code and they are simply using a git
submodule to simplify their own dependency versioning and development.

You might also have to add a new libsrtp version because the one
packaged in Guix is not configured to use openssl unlike telegram
expects. I'd still try the packaged version first if compiling telegram
a few more times isn't a big problem for you.
