After agp8.0 version, how to insert a task after mergeResouces task?

I need to compress the images after the mergeResources task, so that my apk package size can be reduced.

However, artifact api v2 after agp8.0 does not provide a similar channel.

I have no way to use InternalArtifactType.MERGED_RES to build my task execution order.

The question is how to specify a task to be executed after mergeResources and before procesResources task after agp8.0?
