          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
