If you don’t have the experience or tools/equipment you’ll need to take it to a repair shop for micro soldering.
Here’s a YouTube link that shows what’s required:

Although it may look relatively easy it takes a fair bit of skill to master micro soldering without causing damage to the replacement parts or nearby components.
Hope this helps you to decide
