Unable to connect to hidden WiFi network

[pe-jot]

First of all, thank you for all the amazing work done so far!

When trying to set up a TTGO LoRa-32 I struggled to connect to my hidden WiFi network.
After some code investigation I found out that the WiFiMulti class in the version used in the project is scanning for available networks - so it's clear why it cannot find it.

However, when looking into the current Github codebase of arduino-esp32 (version 3.0.4) I saw that there was already an improvement on that:
run(uint32_t connectTimeout = 5000, bool scanHidden = false);

Unfortunately, I failed somehow to make use of this new version, as updating the PlatformIO version to platform = espressif32 @ 6.8.1 did not work out.

My workaround is now that I've grabbed the current WifiMulti.cpp and .h file and put them into the project directly (not nice, but does the job).

Any ideas how to resolve that?
