Problem bundling a mac application

I'm trying to make a mac app bundle. It is bundled around a shell file. The structure is like this:

App
    Contents
        Info.plist
            App.command
        MacOS
        Resources
            App.icns

However, when I double click on the app bundle, it shows the following prompt:

To open classroom.command, you need to install Rosetta. Would you like to install it now?

It seems that my app bundle is not intel-based. But it doesn't make sense. Shell scripts have nothing to do with what platform it is right?

I verified it by getting info on the .app root folder. I can see that the "Kind" is "Application". Whereas on other launchable apps, I see that the "Kind" is "Application (Intel)". Is there something I missed from Info.plist?

It looks like MacOS assumes it's Intel unless told explicitly that it supports ARM64.

I've been able to do that by adding the file /Contents/Info.plist with this contents:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>CFBundleExecutable</key>
    <string>run</string>
    <key>CFBundleIdentifier</key>
    <string>com.testing</string>
    <key>LSArchitecturePriority</key>
    <array>
        <string>arm64</string>
    </array>
    <key>LSRequiresNativeExecution</key>
    <true/>
</dict>
</plist>

Also, the LSArchitecturePriority value seems to be cached (or at least Rosetta would not re-consider running the app)... and it seems that changing the CFBundleIdentifier to anything else was enough to get it to try again.

I don't think this is relevant, but I did see someone mention that arm64 programs needed to be signed, I had been trying to do that with the following (using the ad-hoc identity), but I don't think it's necessary (maybe it's required for binaries):

codesign --timestamp --options=runtime -s "-" testing.app

Rosetta is a piece of software through which PowerPC code can be run on an Intel Mac. Sow depending on your proccessor,OS you might need to instal it to run the application.

here is the full explanation
