How do I get the chain of outputs of a AudioMixerGroup up to the Master?

The title says it all, I think.

I have a SoundSource that plays into an AudioMixerGroup. I can get the MixerGroups’ mixer with AudioMixerGroup.audioMixer but I would like to walk the complete tree of all MixerGroups up to the Master.

something like this: GroupA1GroupAMaster

Getting groups with AudioMixer.FindMatchingGroups(GroupPath) doesn’t help because I have to know what they are called for that.
