How to install old version of icu?

Following a pacman upgrade, I can no longer use ungoogled chromium.

> chromium
/usr/lib/chromium/chromium: error while loading shared libraries: libicui18n.so.75: cannot open shared object file: No such file or directory

This is because icu got updated to 76.1-1, but ungoogled chromium still relies on 75. I browsed AUR but only versions up to 74 seem to be available. How do I manually install icu75 while I wait for a fix?

You rebuild your out of repo packages against the new version, you don't install the old lib.

I tried installing ungoogled-chromium (non-bin version) but it fails:

Do I need to manually edit the PKGBUILD of ungoogled-chromium or ungoogled-chromium-bin? If so how should I edit them?

Re: How to install old version of icu?

I guess ungoogled-chromium also needs to use the vendored version of ICU similar to what our chromium and electron builds did
