DataVerse String maps / Choices in Flow

When needing to set a Choice value in a DataVerse entity from Flow, one needs to use the attribute value (the long number) as opposed to the nice label. How to get this dynamically so it does not need to be hardcoded in the Flow?

The filter rows here is :

objecttypecode eq ‘tm_request’ and attributename eq ‘tm_completionstatus’
