Secret Event links not opening companion

On android, accessing a web link for a secret event takes me to the zwift website - which doesn’t allow me to join a pen (thinks about it but all pens stay the orange + icon).

Cannot make chrome send the link to companion to try there. No matter what I do the link always opens in chrome. I have checked “open default” system settings and they are correct.

Is there a way I can enter event ID and secret within companion to view the event and try to join it?
