Public bug reported:

When an application requests permission to do an screenshot, a dialog
opens that offers the user the possibility of allowing or denying
applications the permission, and says the choice will appear under
Privacy settings. However this is not the case.

If the permission is denied the first time, this breaks the application,
since it can never be granted again.

If the permission is granted, this creates a security risk, since now
all applications can access the screen without an easy way to change the
user choice.

Steps to reproduce:
- Install an application that request permission to screenshots (e.g. flameshot), and execute it.

![The only way I have found to actually modify the choice is to access the dbus interface though Python code:](https://community.upwork.com/t5/Freelancers/Constantly-asking-for-permission-to-share-screenshot-on-Gnome/m-p/1222388#M731300)
```
import dbus
bus = dbus.SessionBus()
perm = bus.get_object('org.freedesktop.impl.portal.PermissionStore', '/org/freedesktop/impl/portal/PermissionStore')
perm_iface = dbus.Interface(perm, dbus_interface='org.freedesktop.impl.portal.PermissionStore')

perm_iface.Lookup("screenshot", "screenshot")
perm_iface.Set("screenshot", dbus.Boolean(True), "screenshot", {"": ["yes"]}, dbus.Byte(0x00))
perm_iface.Lookup("screenshot", "screenshot")
```
