If i click on the "Try Skype Web App" link of an Skype for Business invitation i get a download of an MSI windows installer file... is that a joke? How could that be a **Web** app??
Guys, it's 2019... we have HTML5 in the meantime ;-)
Or please learn e.g. from Telegram how to write a portable desktop app...
