phone's hotspot not working to cast screen

[purplepencil]

Hello sir, first of all thank you very much for this great work, I'm using my phone's hotspot and the raspberry pi connects but nothing appears on the screen, how can I fix this?
And how can we hide the all.sh file? When I start the raspberry pi, the all.sh terminal automatically appears on the screen and the connection codes appear.
Thank you very much...
