TarikTarikH That software exist as a snap package.
or you can use snap-store to search for it if you don't like to use terminal.
EDIT. I made a test by downloading the community version for their website.
If you want to install it manually, I recommend you to save the extracted folder from tarball in $HOME/.local/share, or create a new directory where you want in your $HOME.
To to the folder ../idea-IC-193.5662.53/bin and run the script form terminal ./idea.sh. Automatically the skript will install this app and will create a launcher in $HOME/.local/share/applications/ the jetbrains-idea-ce.desktop which it will be visible in menu and you can pin it to panel.

In my case I created a new directory in $HOME and run the script from there to install it.
See, I think it is running fine
