Using kdeconnect-handler "tel:xxxxxxxxx" to insert a phone number into my Android phones dialer is very handy but how could I go one step further and activate the outgoing call?

I tried kdeconnect-handler "tel:xxxxxxxxx\n" (super lame) but that obviously does not work. In my case, my phones screen is totally corrupt but the phone itself still works. I have a bluetooth headset so answering incoming calls works and by using the tel: URL (if I could activate and call the outgoing number) would allow me to keep using this phone until I can replace it.
