Casting to google hub problem

I want to cast a mealie recipe to google hub.
I come from a long way.
I use mealie as an addon in HA
First thing to do , before able to cast it, it had to be https
Mealie in home assistant is http

So i had to create reverse proxy using nginx manager… Then create a subdomain in cloudflare, and setup a reverse proxy in nginx manager + ssl certificate
Then i had to open 2 ports on my unifi setup
Now i can reach it from https
Next i created a button in home assistant to start a script where i start casting to a google home hub in my kitchen
This works
I can now see mealie on my hub, + i can even scroll in mealie
However
Before getting in mealie, i need to log in mealie
And there im stuck.
Cause when i set my cursor in my user field (or even password field) , i dont get a keyboard to type, so i cant log in
Stuck here
Really looking forward for a solution for this

Casting from phone is not a good idea cause you cant scroll on the hub
Who can help so i can type in or something?

Anyone any ideas/tips?
