How to migration frozen index to hot or warm?

Hello I'm InJong from korea.
I have a frozen indices with datastream. (in Elastic Cloud)

I want to move frozen tier index to another tier. (hot, warm, cold)

I checked document
-> "Migrate index allocation filters to node roles | Elasticsearch Guide [8.5] | Elastic"

But i didn't understand how to migrate.

Can you tell me api step by step?

FYI frozen indices are deprecated - Unfreeze index API | Elasticsearch Guide [8.5] | Elastic

Once you have unfrozen them you need to allocate them to the tier that you want using Cluster-level shard allocation and routing settings | Elasticsearch Guide [8.5] | Elastic
