Filter on an enum for GraphQL query

I am having trouble filtering by an enum in my GraphQL query. In a REST API call, I can just user a string for the query. However, this seems not to work with GraphQL. Here is the query I’m trying to run:

{
  actions(
    filters: {
      action : {
        teamRole: {
          eq: "leader"
        }
      }
    }
  ) {
    data {
      id
      attributes {
        action {
          name
          duration
          description
          teamRole
          type
          successRate
          targetsNode
          targetsEdge
        }
      }
    }
  }
}

This does not work without quotes either
