Installed thonny using sudo but can't run from desktop

Ubuntu 22.04.4 LTSkubuntu 22.04

I downloaded the thonny bash script from thonny git.from terminal i typed sudo bash thonny-4.1.4.bashit installed fine.If I run in terminal sudo /root/apps/thonny/bin/thonny it runs and opens fine.If I try and run it from Kubuntu desktop I get an error that the file doesn't exist. I'm guessing that as my user I don't have access to that file being that its in the root folder.

Question:
Why are files installed into root folder with root user:group permissions when I use sudo, if I can't be root to run the app from the desktop?

I always follow install instructions which always reference using sudo sothis goes for everything I do resulting in lots of permission denied errors but thats for another day.Thanks for your help,Kadam.
