All permissions can be even overridden by the user doing cli commands or using flatseal to add more permissions.
Example arguments:
```
finish-args:
- --share=ipc
- --share=network
- --device=all
- --filesystem=home
- --filesystem=/run/media
- --filesystem=/media
- --filesystem=/media
```
In this example we're telling the flatpak:
Enable ipc and networking
```
--share=ipc
--share=network
```
Have access to all plugged in devices, such as controllers and webcams.
```
--device=all
```
Have access to file systems paths for the entire home catalog and plugged in Disks / SDCards and USB Storage.
