How to solder this back without a hot plate?

Ok … this connector came out no damages to the connector itself.. but I don’t know how to solder it back without melting the plastic ..

I have an electric stove top that I can put a 5mm aluminum plate on top and put only this cornor of the pcb on it but I don’t have a thermometer to measure

I know it seems like I’m about to do a r/techsupportmacgyver kind of maneuver so that’s why I paused and cane here to ask

And here are the tools I have and I can’t order stuff from online like a hot plate it will take very long time in my country

So

I have a soldering pen Flux Solder paste and normal solder too

I’m good with the soldering pen and never did a reflow with a hot plate

No oven .. but I have a hot gun but it’s too big and very hot on low settings and afraid to melt the plastics before melting the solder

Any suggestions would be appreciated
