Launch different app

Hi, I'm creating a macOS app for private use. From that app i would like to launch a different app from a button click. The problem is that the app i want to launch doesn't have a URL scheme. I've checked in the apps plist and reached out to them but no URL scheme. Is there way to do this without the URL scheme? I don't want to use Apple script.

I'm using SwiftUI.

Can someone please help me?
