Configuring the firmware
Once you have opened the project, you should see something on the left side like this
Open the platformio.ini file
On lines 17 and 18 replace the placeholder text with your correct SSID (WiFi access point name), and password respectfully.
CAUTION
Make sure your wifi router has a 2.4 GHz band. While most do, this is not always the case. Setting each band (5GHz, and 2.4GHz) to different SSIDs is recommended, though not required.
Double check that you have correctly entered your WiFi credentials and that said wifi network has a 2.4GHz band.
