MongoDB Atlas App Services & Realm Atlas GraphQL API

Hello Team,

How do you pass OR condition in graphql query under variable?

For e.g.
If graphql query needs to return all schema fields for a document where expiry date is either empty or for future. Currently if i pass OR operator in query, it gives me an error that OR is unknown field in schema.

Thanks
