How to Reset password using php active directory graph api?

Hi
I am php web developer.
I have setup azure graph api using github https://github.com/Azure-Samples/active-directory-php-graphapi-web for add update azure user detail.
add update work great.
but when i update user with password
it will give me error " Insufficient privileges to complete the operation ".
I give all the required permission.

I also follow this https://developer.microsoft.com/en-us/graph/docs/api-reference/v1.0/api/user_update but can't success
Is there any special permission for update password of auzre user
because add with password works fine.
only issue occur in updating password.
Any help appreciated

Thanks
