Permit2

[devrus91]

Dear Sir,
I have a smart contract that uses https://github.com/1inch/solidity-utils/blob/e1686b3cfc520303f5b741bf2223173e529bcee4/contracts/mixins/PermitAndCall.sol#L4 to handle permit and action execution in a single transaction.
to call it in js it is possible to use https://github.com/1inch/solidity-utils/blob/master/src/permit.ts#L192
I tiried to reproduce that function in dotnet but no success
Here is eample of how we use that in js test

    it("Method: BySig then SponsoredCall then PermitAndCall then deposit", async function () {
            const {token, contract} = await baseSetup()

            await token.transfer(user_1.address, SIX_USDT)

            const permit = await getPermit(
                user_1,
                token,
                '1',
                CHAIN_ID,
                await contract.getAddress(),
                SIX_USDT,
                await timestamp() + 100
            )

            const tokenPermit = ethers.solidityPacked(
                ['address', 'bytes'],
                [await token.getAddress(), permit]
            )

            const depositCall = contract.interface.encodeFunctionData('deposit', [SIX_USDT, false])

            const permitAndCall = contract.interface.encodeFunctionData('permitAndCall', [tokenPermit, depositCall])
            const sponsoredCall = {
                traits: buildBySigTraits({deadline: 0xffffffffff, nonceType: NonceType.Selector, nonce: 0}),
                data: contract.interface.encodeFunctionData('sponsoredCall', [await token.getAddress(), SIX_USDT - FIVE_USDT, permitAndCall, "0x"]),
            }

            const signature = await user_1.signTypedData(
                { name: 'XXXXX', version: '1', chainId: CHAIN_ID, verifyingContract: await contract.getAddress() },
                { SignedCall: [{ name: 'traits', type: 'uint256' }, { name: 'data', type: 'bytes' }] },
                sponsoredCall
            )

            await contract.bySig(
                user_1.address, sponsoredCall, signature
            )

            expect(await token.balanceOf(user_1.address)).to.be.eq(0n)
            expect(await contract.balanceOf(user_1.address)).to.be.eq(SCALED_SIX_USDT - (SIX_USDT - FIVE_USDT))
        })

May be some functionality of that package can help to implement that permitAndCall?
