SalesAgreements GraphQL Query Filtering

[Lawson_Thalmann]

I'm trying to use the SalesAgreements GraphQL API and I barely know anything about GraphQL to be honest up front. I'm trying to filter by SalesAgreement.reason = ORDER_EDIT. I've tried putting it everywhere in every format I can find online, but it's not taking any of it. I'm sure this is really simple for someone who knows what they're doing?

query timeStampVars($happened_at: String) {
  orders(first: 5, query: $happened_at) {
    edges {
      node {
        id
        agreements(first: 5, query:reason:ORDER_EDIT) {
          edges {
            node {
              happenedAt
              id
              reason
              sales(first: 5) {
                edges {
                  node {
                    ... on ProductSale {
                      id
                      lineItem {
                        sku
                        variant {
                          id
                          sku
                        }
                      }
                    }
                  }
                }
              }
            }
          }
        }
      }
    }
  }
}
