Google script "publish as web-app" adding personal font

in the google script I am testing some shit at the moment. And I also want to have my own font in the web-app. As I already searched for "own fonts @my Website" I always stuck at the point, that I need to upload the font file and get it with "@font-face", but that is obviously not possible in the web app, isn't? The mehtod is a local link to my driver where I put the font.TFF (or whatever) but then only ppl who installed the font got the real Text font on the web app. A solution (I hoped to be one) was to link the file of my google drive, but then does not work as well, even when I get the "real" link with the Google drive link generator.... Hope anyone unterstands my problem, I am rly done right now ._. Thanks
