I have a list of rs id from a GWAS dataset like this GWAS data set with rsIDs

I was wondering :

a) If and how can I use the GraphQL API from open targets to query rsID and

b) Is it possible to make a query for multiple rsIDs (e.g. list in csv format ) ?

I checked an issue in opentargets that rsID is not supported and must be transformed into ID by using a search endpoint but the example is not working anymore (https://community.opentargets.org/t/querying-using-rsid/225).

Do you have any idea how to do it with GraphQL?
