Are older versions of GarageBand available anywhere?

Can't install garageBand using AppStore on Mojave 10.14.6. Apple support says I have to upgrade to Big Sur to use GarageBand which is unacceptable for me.
It seems strange to me. Mojave is still supported, there was a version of GarageBand that used to work with it. I can't believe GarageBand developers deleted older versions from their private repositories. Is there a chance I can get a Mojave compatible version of GarageBand?

Did u ever figure this out? I have the same issue
