no icon on menu Ubuntu 20.04

I can’t delete Etcher from opt directory folder as i followed on this site:
[https://linuxhint.com/install_etcher_linux/]

I then re-downloaded the file and put in a folder in my home directory so i can use it.

But either way i don’t have an icon in the menu. Why? balenaEtcher 1.5.90

The AppImage version is a portable version, so it doesn’t install anything (including menu entries). There is no reason to put the executable in /opt either, and you can remove it with:

$ sudo rm /opt/balenaEtcher-1.5.90-x64.AppImage

(always be careful when running sudo)

To install Etcher locally, follow the instructions here for your distribution.
