Sure its possible
You can create a launcher of whatever you want this way :
write a file inside there :
sudo nano /usr/share/applications/myweblink.desktop
Put inside :
[Desktop Entry]
Name=Google Duo
GenericName=Google Duo
Comment=Open Google duo inside chromium browser
Exec=chromium-browser --app=https://duo.google.com/
Icon=/usr/share/icons/google_duo.png
Terminal=false
Type=Application
You can replace chromium-browser with google-chrome or firefox
Do not forget to download also a icon file .png and put them inside /usr/share/icons/
