Error 908: the permission write_external_storage has been denied. please enabel it in the settings app

Hi everyone, i got a problem doing my program, im trying to recive information from a PIR sensor and recive the data here on the appliation, but I got this error when i scan the QR, and its not a code error, and my android is A34, i have given all the permissions and didnt work, i dont know what else i can do.

There is no WRITE_EXTERNAL_STORAGE permission on Android 11+.
Why do you believe you need storage permission(s)?
