Environment details

Android API 35
Library Version: 6.1.1

Steps to reproduce

1. Create a GoogleMap composable with a Clustering composable inside of it.
2. The Clustering's ItemContent and ClusterContent params are setup with custom composables which have their contentDescription set to different texts(i.e. for cluster: "Cluster of x items" and for markers "Marker with y title").
3. Activate Talkback on the Android OS.
4. Run the app
5. Try to select a cluster or a marker
6. Actual result: Talkback says "Map Marker" instead of the expected "Cluster of x items"/"Marker with y title"

Code example

This is an example how we have setup the renderer for the Clustering:

 val renderer = rememberClusterRenderer(
        clusterContent = { cluster ->
           ClusterContent(
                numberOfItems = totalItemCount,
                isSelected = isSelected
            )
        },
        clusterItemContent = { mapItemGroup ->
            if (isStacked()) {
                StackedMarkerContent(
                    items = items,
                )
            } else {
                CustomItemMarkerContent(
                    item = items.first()
                )
            }
        },
        clusterManager = clusterManager
    )

Please note that i've noticed that in the top left corner of the map there are some invisible marker/cluster views which are selectable by talkback and those have the content description correctly read by talkback.
