How to execute binaries from $PATH from flatpak applications

Let's say you don't want to install Visual Studio Code from their package repository but use the flatpak package instead. This works but as soon as you try to execute any binaries from your regular PATH they won't be found since that's blocked by the sandbox. Even giving full host filesystem access won't work reliably because that filesystem will be mounted under /run/host which messes up any absolute paths which are often baked into the most unexpected places.

After lots of digging I found this solution from the qutebrowser flatpak maintainer. Just in case Reddit dies a copy can be found below.

I assumed that the mentioned flatpak-spawn-wrapper was a feature shipped in all flatpaks but it looks like only flatpak-spawn is included and that wrapper is a [script](https://github.com/flathub/org.qutebrowser.qutebrowser/blob/master/

Make the Ubuntu Zoom client automatically switch Bluetooth headset profiles to HSP/HFP
#!/bin/bash
# This is a hack to make Bluetooth headests like the jabra Evolve 65 actually
# work as a headset with the Linux (Ubuntu/Debian) Zoom client without having
# to switch manually from A2DP to the HSP/HFP profile.
#
# This is done by injecting an environment variable which makes PulseAudio
# recognize the application as a telephony/voice application as described
# here:
