Swap execution action requiring the user to sign the provided PSBT and then submit it back via the provided `submitPsbt()` function, has two variations:

* `"FUNDED_PSBT"` - A ready to sign PSBT with the inputs populated from the provided bitcoin wallet address
* `"RAW_PSBT"` - Raw PSBT without the inputs, the implementor needs to add the input UTXOs before signing the transaction (also make sure to set the `nSequence` field of the 2nd input, index 1, to the provided `in1sequence` value)
