I am making project using this video-

https://www.youtube.com/watch?v=gpaq5bAjya8

I am done making the AR & problem I am facing is at "Build & Run".(26:40 timestamp of video)...while deploying the app on the device(my phone Redmi 9{I have enabled developer option & USB debugging both}..yet error keep coming. "Profiling is for development option"

(Note- before that I tried to run project on oppo A3 where the project was uploaded on smartphone but since that phone version don't support google ar core so i switched to Redmi}

I am new to Unity so I don't know much about it!! Help!!
