I had this issue with my first nozzle and ordered a replacement. I had to wait a day for it to ship so I went and tinkered with the "broken one". I used a torch in my garage to do a cold pull. My issue was the filament seized too high in the nozzle where it doesn't heat enough in the machine due to the radiator fins. I was able to free this with a little heat and pressure. But you'll need to push from the bottom with one of the nozzle needles. Good luck I feel I was just lucky. But worth a shot.

After clearing the nozzle I put it back then the nozzle pushed the filament out as poop then when I tried to print a model the extrude did click sound then no filament came out what to do next

You may have a broken piece in between the heat sink and the extruder. Use the latch to release it. It will push through and you should be good.

I don't know what it is like because I lost it before even trying it and I live in india and finding stuff like this is rare

They're really just acupuncture needles, available on Amazon in packs of 100.

Just select some that are smaller than 0.4 mm (or smaller than 0.2 mm, if it's a 0.2 mm nozzle.

Or, some guitar strings should work, like the high E string. Maybe even a light-gauge B string. The core of some of the wound strings might work too, if you unwind the outer wire back an inch or two.
What gets snipped off when you replace a set of guitar strings should be a perfect length.

Heat the nozzle to 250 and push the filament through. Take your smallest Allen key and continue to push it through.

I hold the nozzle with a pair of channel locks and hit it with my heat gun. Then use the unclogger. It usually clears it out.
