Is WRITE_SETTINGS permission compulsory?

[iadeelzafar]

I'm wondering if WRITE_SETTINGS permission is compulsory to toggle the hotspot? I can't find it anywhere in the WifiManger class or setWifiEnabled method's prerequisites.
CHANGE_NETWORK_STATE is what's written in the setWifiEnabled method as a prereq.

It's quite related to the kind of a project i'm working on. I'm trying to turn on wifi hotspot on an android device programatically and then host a server on that ap. So, I've already implemented the solution but I've some confusions that I'm unable to figure out.
This is the permission that is required before turning on the wifi hotspot.

I'm not sure if asking this permission is the the only way to toggle hotspot. I'm trying to figure out if there's any other way to ask this permission apart from this external screen. Since this activity is not opening on some devices.
Here's a link to the repo.

The hotspot integration can be found in the helloServer branch. If my message is not clear, please let me know.
Thanks for your time!
