First IPO allotment (SBI Funds IPO) – Should I hold or sell?

This is my first-ever IPO allotment, so I'm completely new to this.

I got allotted shares in the SBI Funds IPO, but the listing gain was much lower than I expected. I'm confused about what to do now.

Should I:

Sell on listing and book whatever profit there is?

Hold for the medium/long term?

Or wait a few days to see how the price moves?
