How to add icon to one custom package

My problem is that I’m not able to add an icon to the custom package. I already read in several places that it is only possible by in an online repository, is it true?
There is no way to add within the custom package itself?

There is, the icon just needs to be hosted somewhere as the .ico is not included in the package itself.

Try putting ‘https://da.wikipedia.org/static/favicon/wikipedia.ico

Hello! Just like MikkelFrid said, the file needs to be uploaded somewhere and you need to use the URL.
