tl;dr - do what you want, I hold no liability for usage/misuage of this note.

Check the currently installed version of Steam (or other application) using flatpak info then install the SAME version of MangoHud as indicated in the Freedesktop runtime!
```
flatpak install org.freedesktop.Platform.VulkanLayer.MangoHud
```
Check whether and where a specific version is installed
```
flatpak info --show-location org.freedesktop.Platform.VulkanLayer.MangoHud
```
(optional) Create a personalised config file (Goverlay recommended!) in ~/.config/MangoHud/MangoHud.conf ~~and copy it over to~/.var/app/com.valvesoftware.Steam/config/MangoHud/MangoHud.conf~~
```
https://raw.githubusercontent.com/flightlessmango/MangoHud/master/data/MangoHud.conf
```
Enable RO permissions (optional) $XDG_CONFIG_HOME stands for $HOME/.config
```
flatpak override --user --filesystem=xdg-config/MangoHud:ro
```
You can later remove it using e.g. Flatseal under "All Applications" and "Filesystem" tab.

(optional) To enable MangoHud for all Steam games (globally):

flatpak override --user --env=MANGOHUD=1 com.valvesoftware.Steam

Run Steam games using e.g.

mangohud gamemoderun %command% -vulkan
MANGOHUD=1 gamemoderun %command% -vulkan
mangohud %command% -vulkan
