Pushpin in tyre, pulled it out and there seemed to be a leak, but no loss of PSI and the leak doesn't seem to be happening anymore?

Hey! I was washing my car and found a pushpin in the shoulder of my tyre (and it was only a month and a few days old too 😭😭). I'm based in Australia, so afaik (and according to the few tyre shops that I phoned up) it's illegal for reputable folks to repair because it's too close to the bloody sidewall.

I'm probably a bit dumb for doing this, but I did the detergent test to check if the tyre had been punctured enough to spring a leak - it didn't seem to show anything under the pin, so I carefully pulled it out. Immediately before that, I'd checked the tyre in question on the dash and it read that it was at 270 kPa (maybe 20 higher than standard for a Mazda 3? I hadn't put air into it since I got the new tyres from the shop so I assume that's close to what it had been out of the shop). The opposite healthy tyre was 260.

I shone a light on where the puncture was after pulling the pin, and there appeared to be tiny bubbles foaming out slowly from where the puncture was. That's what the video is of. Sorry my camera works a bit shit 😅 was in a silent bummed frenzy when I saw the foam come out, so I didn't think to record a better video cos I assumed the tyre was done for regardless.

It was pretty late at this point, so I decided to leave it for the next day, but when I went to check it, the car had lost no pressure, still sitting at 270 kPa. When I sprayed the tyre again in the exact spot, I could see no leak.

I imagine that I'll probably still have to mount the spare, drive out and shell out the big bucks to get it replaced, but would love to get some opinions on this. Doesn't hurt to ask 🤷‍♀️ I feel like a bit of an idiot so I'd really appreciate any help or experience. Do I need to get it replaced and, if so, do you think that it's okay to drive on to the tyre shop 2km away? Or do you think this could possibly be repaired? Or am I missing something completely that I haven't considered 😅?

Thank you so much, really appreciate any help! Feel free to call me out if what I did was stupid, cos I would really love to know what best practice should be the next time it happens.
