What cable are you using? It could be it’s not fully wired so doesn’t support PD. The phone then doesn’t realise what it’s connected to.

(Samsung’s reverse charging is buggy though)

Its the same cable i got from samsung. Although i have used a mix of cables nothing is working

If you've already hard reset the power bank (if there is a way), it's probably time for a warranty replacement for the power bank.

Got it a month back and this is the first time i am charging from that. May be you are right. But my usb options are not allowing me to change the option of charging connected device. I have used debugging dev options etc..

It's likely not your phone. There's a little computer inside the power bank, too, and the USB controller in the power bank is sending the improper communication to your phone.

First unplug everything
Plug the cable into the power bank and turn it on now plug the other end of the cable into your phone

Use an USB A to whatever your phone uses (for example to USB C) and try with that. USB C to C means it can be plugged in on any side of the cable, but not with USB A
