[Bug]: This snap lacks basic features when compared to the apt-installed version of OBS

What happened?

This snap doesn't have Twitch-specific docks, doesn't allow Twitch chat addons, doesn't load plugins, etc. (I did put the plugin in ~/snap/obs-studio/plugins)

What should have happened?

Given that the apt-installed version from OBS's PPA doesn't have these problems, this snap at the very least should not be recommended to Ubuntu users. However given that the OBS project also provides an official Flatpak, what's the point in maintaining this snap at all? Forgive my bluntness but I wasted quite a bit of time trying to get this snap to work.

  **Connecting Interfaces**

  For the best experience, you'll want to connect the following interfaces.

     sudo snap connect obs-studio:alsa
     sudo snap connect obs-studio:audio-record
     sudo snap connect obs-studio:avahi-control
     sudo snap connect obs-studio:camera
     sudo snap connect obs-studio:jack1
     sudo snap connect obs-studio:kernel-module-observe

  **NDI**

  If you want to use the NDI plugin you'll need to connect the Avahi Control interface.

     snap connect obs-studio:avahi-control

  **Virtual Camera**

  Starting with OBS 26.1.0, Virtual Camera support is integrated. Here's how to install and
  configure `v4l2loopback`:

     sudo snap connect obs-studio:kernel-module-observe
     sudo apt -y install v4l2loopback-dkms v4l2loopback-utils
     echo "options v4l2loopback devices=1 video_nr=13 card_label='OBS Virtual Camera'   
     exclusive_caps=1" | sudo tee /etc/modprobe.d/v4l2loopback.conf
     echo "v4l2loopback" | sudo tee /etc/modules-load.d/v4l2loopback.conf
     sudo modprobe -r v4l2loopback
     sudo modprobe v4l2loopback devices=1 video_nr=13 card_label='OBS Virtual Camera'
     exclusive_caps=1

  **NOTE!** Using `video_nr` greater than 64 will not work.

  **Removable Storage**

  To access content on external storage, connect to the removable-media plug:

     snap connect obs-studio:removable-media

  **gPhoto**

  The gPhoto plugin allows some DSLR cameras to be connected via USB. You'll need to connect the Raw
  USB interface.

     snap connect obs-studio:raw-usb

  **3rd Party plugins**

  To install pre-compiled plugins, download and extract the plugin to
  `~/snap/obs-studio/current/.config/obs-studio/plugins/`.

  This is how the Input Overlay plugin looks when correctly installed:

     /home/username/snap/obs-studio/current/.config/obs-studio/plugins/
     └── input-overlay
         ├── bin
         │   └── 64bit
         │       └── input-overlay.so
         └── data
             └── locale
                 ├── de-DE.ini
                 ├── en-US.ini
                 └── ru-RU.ini

  If you want to use the Input Overlay plugin, you'll also need to connect the joystick interface:

     snap connect obs-studio:joystick

  - obs-studio.eglinfo
