Using OSC can I determine which layers are inside which groups?

[SeanBannister]

Is there a way to determine which layers and groups are associated via OSC?

Here's my use case... When you add a new layer in Resolume all existing layers change ID. Therefore in my code I'm grabbing the names for all layer ID's and groups using:
/composition/groups/${groupId}/name
/composition/layers/${layerId}/name

But I've realized I need to know which layers are in which groups. With the goal of creating variables to reference them like:
group1.layer1

I've noticed it's possible via the Rest API: /api/v1/composition/layergroups/1

For anyone else looking for a solution using the Rest API instead of OSC I posted some javascript code here:
