Payout on IDCW funds

Hi,

If I purchase IDCW mutual funds on Coin, how is the monthly dividend paid out for IDCW mutual funds (Kotak Debt Hybrid Fund IDCW Monthly, Parag Parikh Conservative Hybrid Fund IDCW Monthly)?

Is the pay out done as payment to bank account, or is it the payout done by crediting additional fund units back to the holders demat account?
