macOS says I need to install Rosetta, but it isn't true

I've downloaded DavMail-MacOSX-6.3.0-3627.app.zip and tried to use it on an M4. When I click on DavMail.app, macOS says I need to install Rosetta. However, that isn't true, since the package contains a shell script, which runs a Java app.

In fact, when I run DavMail.app/Contents/MacOS/davmail from the command line, DavMail starts without issues, the same when I run it from the bare .zip davmail-6.3.0-3627.zip.

While it's not a big issue, I'd like to be able to run it from a macOS package format, since this makes adding it to the login items easier. I guess it's about adding a download for Silicon Macs, while the current one is for old Intel devices. Would this be possible? I could also repackage it on my own, using the macOS Automator, yet having a public download would be simpler for anyone who needs it.

Thanks.
