Cannot connect a ESP8266-01S module to a hidden network

Using Arduino Networking, Protocols, and Devices
1

Hello all, I am using a ESP8266-01S module with a Arduino UNO. For my project, I require it to connect to a hidden network (the settings of which I have no access to). I have been using AT commands to operate the ESP, and am attempting to use the "AT+CWJAP" command to connect to WiFi networks. The command works fine with non-hidden networks, but cannot seem to connect to networks with hidden SSIDs or iPhone hotspots. I have attempted updating firmware, changing the protocol standard, and using fast scan, but none of these solve the issue-- the command always fails with the 3rd error code: cannot find the target AP.

My circuit schematic can be found in this video at 1:01: https://www.youtube.com/watch?v=YKn2ZXYb_EI

My full ESP setup code, if helpful, is here: https://github.com/throwaway3141/esp-setup/blob/main/SetupESP.ino

Is there any way to connect the module to a hidden network? Would an NodeMCU ESP8266 fare better in this regard? I am at my wit's end trying to solve this-- any help is appreciated. Thank you.

According to the Net, it is a known issue, which they tried to fix several times, but never
succeeded.

I had found this thread, but it is referring to the accessibility of the AP mode of the ESP, not as a station. Do you know of information regarding connecting to hidden networks in station mode?
