No there are not. I just downloaded the package and placed it in my user bin, like I always did on Leap.
The software do come with .desktop files, but TW doesn’t do anything with them.
But on Leap, when you double click on a .desktop file, it asks if the file can be trusted. When you say yes, it runs the application and a shortcut will appear in the menu automatically. I would think that Tumbleweed would have a similar working.
When I look on my old Leap system, I do not have shortcuts for these application in the location you mention, yet they all have an icon in the menu and when I double click on the executable, it runs.
Quick test does not show any difference here (on two VMs). Check MIME type of files under Leap and TW and check default handlers for this MIME type in each case:
