The motoko implementation has been completed, but the call of approve and transfer has not been implemented for this reason.

// TODO:Can not perform call in a generic way,I am looking for a solution

          private func _executeCall(receiver: TokenHolder, callData: CallData) : async Result.Result<Bool, Text> {
            switch(receiver) {
              case (#Account accountID) {return #ok(true); };
              case (#Principal principal) {
                if(PrincipalExt.isCanister(principal)){
                   return #ok(true);
                }
                else return #ok(true);
              };

how to test Motoko implementation?

git clone from here , then run
