App doesn't work on MacOS Catalina 10.15

There's another issue about this but it has been closed without a solution so I'm making a new one.
I'm running MacOS Catalina 10.15 on a Mac Pro 2018 and when opening the app (no matter if portable or installed) the following window pops up:

FYI, latest version of Firefox has their own export feature now.

I just tried it yesterday and it worked fine for me.

Well I did and it didn't work, that's why I'm trying to use this app in the first place

Just open manually the binary inside the .app, i.e:

download the app tarball
uncompress it
run from the terminal ./FF-Password-Exporter-1.2.0-mac/FF\ Password\ Exporter.app/Contents/MacOS/FF\ Password\ Exporter
which should work
