      }

      message NftTokenApproveAllResult{
        bytes owner_address = 1;
        repeated NftAccountTokenRelation approve_list= 2;
      }
  
     //use NftAccountTokenRelation but should keep this fields
      message NftAccountTokenRelation{
        bytes owner = 1; //owner account
        int64 total = 4; //total token delegated
