It's going to require a soldering iron, and essentially flux to oxidize the solder, solder wick to remove old solder and solder wire to melt some new solder for putting the new or same charger port back on if usuable.
Sometimes it's just loose and needs to be resoldered.
But it can be physically damaged inside the charger port instead which would require it to be replaced.
If you are not familiar with desoldering and soldering charger ports search for videos on tutorials on how to do so.
Otherwise take it to a repair shop that does charger port repairs or replacements.
