Is it possible to obtain policy script with graphql?

I’ve been putting together an NFT browser (Wytchspace - NFTs) but have hit a dead-end when trying to source the script for a given mint policy id.

Is it even possible to do this with graphql?

(Even knowing that it is not possible would be helpful - to save me barking up the wrong tree)

Any advice gratefully received!

An update to this: It appears you can pull out the mint policy script (at leas the hex encoded 28 byte hash) if you know the transaction id. So a query to first find the original transaction id (limit 1, order by slot) is required.

There may be more eloquent ways, but this works for me.
