ARCore overwriting Android permission

Hi, I have a screenshot taking function that ask permission from the start to ask permission to write storage so that it can save whatever screenshot it takes into the phone.

It works great in Vuforia but when i use it in ARCore, it did not ask permission to allow storage write and i have to allow it within the phone's Setting>App when i first install my app.

Are there anyway i can add in the permission into ARCore's script somewhere?

Thanks in advance!
