App Call Inner Transaction - missing arguments field?

[mangoplane]

Hi,

Trying to do an inner transaction that's an application call to a specified application index with arguments provided in a way that allows for any application to be called, with any arguments. As far as I can tell, there's no way to specify the arguments at the moment. Maybe it is yet to be implemented?

See: https://github.com/FrankSzendzielarz/AlgorandVisualStudio/blob/main/Transactions/InnerTransactions.md
for inner transaction docs. Below the AppCall class spec is given.

namespace AlgoStudio.Core
{
    public sealed class AppCall : InnerTransaction
    {
        public ulong NumAppArgs { get; private set; }

        public ulong NumAccounts { get; private set; }

        public ulong NumAssets { get; private set; }

        public ulong NumApplications { get; private set; }

        public ulong GlobalNumUint { get; private set; }

        public ulong GlobalNumByteSlice { get; private set; }

        public ulong LocalNumUint { get; private set; }

        public ulong LocalNumByteSlice { get; private set; }

        public ulong ApplicationID { get; private set; }

        public ulong OnCompletion { get; private set; }

        public byte[] ApprovalProgram { get; private set; }

        public byte[] ClearStateProgram { get; private set; }

        public ulong ExtraProgramPages { get; private set; }

        private AppCall()
        {
        }

        public AppCall(ulong numAppArgs, ulong numAccounts, ulong numAssets, ulong numApplications, ulong localNumUint, ulong localNumByteSlice, OnCompleteType onCompletion, ulong? globalNumUint = 0uL, ulong? globalNumByteSlice = 0uL, byte[] approvalProgram = null, byte[] clearStateProgram = null, ulong? extraProgramPages = 0uL, ulong? fee = 0uL, ulong? firstValid = 0uL, ulong? lastValid = 0uL, AccountReference sender = null, ulong? txType = 0uL, byte[] lease = null, byte[] note = null, byte[] rekeyTo = null)
            : base("appl", fee, firstValid, lastValid, sender, lease, note, rekeyTo)
        {
        }
    }
}

Kind regards.

The reason I need this inner transaction, is I'm trying to make an "escrow wallet" that allows for arbitrary inner transactions to be called to simulate a generic wallet, with some basic management applied on top. Perhaps you can think of an alternative way to do an application call, from the contract account, that's triggered externally?
