[Error] xdg-open doesn't work, opening browser link fails

**Describe the bug**

Apps trying to open link in browser fail.

**To Reproduce**

Run `xdg-open https://unity.com` in container.
It doesn't work (nothing happens).

The same command works fine on host.

Also, I was trying to make it work using `distrobox-host-exec`, but it seems to not work for me at all.
From examples `distrobox-host-exec --help`
running `distrobox-host-exec podman ps -a` shows nothing (no output) in container,
while on host `podman ps -a` works fine and gives the list of running containers.

To fully reproduce, create a new container and install Unity Hub:
```sh
distrobox create --name unity-box --image ubuntu:24.04
distrobox enter unity-box
cd
sudo apt update
sudo apt upgrade
sudo apt install libasound2t64 # it's needed for Unity Hub

# Unity Hub
wget -qO - https://hub.unity3d.com/linux/keys/public | gpg --dearmor | sudo tee /usr/share/keyrings/Unity_Technologies_ApS.gpg > /dev/null
sudo sh -c 'echo "deb [signed-by=/usr/share/keyrings/Unity_Technologies_ApS.gpg] https://hub.unity3d.com/linux/repos/deb stable main" > /etc/apt/sources.list.d/unityhub.list'
sudo apt update
sudo apt install unityhub

unityhub
```
It should open a window Unity Hub with buttons/links that you can click and see that they don't work
(nothing happens when you click them).

**Expected behavior**

I'm expecting to be able to log in using links from container's apps (like Unity Hub).

**Logs**
