Libgstgl-1.0.so.0 not found

Hi, I am trying to move a snap package ‘volsung’ from core18 to core20. The build works fine, but when I try to run one of my snapped applications via volsung.signy I get the following:

/snap/volsung/x5/bin/signy: error while loading shared libraries: libgstgl-1.0.so.0: cannot open shared object file: No such file or directory

Here’s the complete yaml file, any help would be appreciated:

name: volsung
version: 1.18.2
summary: Geothermal Simulation Package
title: Volsung
description: |
  The Volsung Simulation Package contains the following applications for geothermal simulations:

  - Brynhild for coupled reservoir/wellbore/surface simulations
  - Gudrun for standalone wellbore simulations
  - Sigrun for standalone pipeline simulations
  - Swanhild for numerical pressure transient analysis
  - Signy - a thermodynamic table tool (including python wrappers)
  - Sigurd - command line tool for running simulations
  - Atli & Gunnar - inverse modelling companion tools for Gudrun & Brynhild

Found it; I had to add libgstreamer-gl1.0-0 to the stage-packages section. The library is required by the new Qt6Multimedia library.
