Add space to BM Instance post creation

Summary

Add space to BM Instance post creation

Content

I created a  BM database Instance using Terraform

When i initially created the BM.DenseIO2.52 instance , I specified BM-DataStorageSizeInGB  = "256"

I could  successfully provision  the database

At some point in the future if i need to add more disk storage in BM Instance ---I  need to understand options

Per the documents we can grow the BM.DenseIO2.52 instance to 11.3TB with High Redundancy

How do i change now with a running database BM.DenseIO2.52 instance to have more storage?

Is there a process available that we can use to allocate remaining space from 11.3TB to our instance?
