What happens when I don't exit my cash secured put position on expiry manually?

I have taken a cash secured put position on one of the F&O stock which is expiring on 28th Nov 2024? The stock has surged a bit now. If I do not exit the position on expiry then what will happen?
considerations are:
the stock is away from strike price and is unlikely to return to the strike price so, I may not have to own the stock. In this case, do I have to exit the position manually before 3:15pm on 28/11 or will it auto settle by crediting the premium into my account?
This is my first ever option trade on selling and hence, require some clarity.
Hope to see some guidance through replying to my query.

Hi @Sweta, Welcome to MadeForTrade Community!

If you hold an OTM contract on expiry day then it will expire worthless. In case of short-sell position, the premium is credited immediately after creating the position; while you square-off or settled by exchange, the premium amount (if any) will be debited as a buy order.

For any ITM contract, the physical settlement will be applicable and the position may get squared-off if the margin obligation is not fulfilled.

Thanks @Renvick_Austin for responding.
Am I right in assuming that If I hold short-sell OTM position, then I don’t have to square it off manually on expiry date? if I am ready for physical settlement or delivery or shares, and if the short sell position still remain OTM on expiry date that would mean, it would expire worthless without me taking action to square it off before 3:15 pm and I will keep the credited premium and it will not incur any overhead expense?
