Each package in APT has a specific name. If you are unsure of the specific name, you can use the apt search function to correctly I.D. the package that you want.
In my terminal, I have an add-on for Z Shell (zsh) that does this for me. So if I type what I want, it offers the name suggestion based on what apt search shows as present in the repositories.
Many apps are Third- Party and are not in the Zorin or Ubuntu main repository. You must look those repositories up which will also yield the package names inevitably.
