Using Gravity: 4-Digital LED Segment Display Module (Red)

connected to FireBeetle 2 ESP32-E IoT Microcontroller with Header with Gravity: IO Shield for FireBeetle 2 (ESP32-E/M0)

My problem is that my code wont compile

when trying to upload code I get this error :

Error compiling for board FireBeetle ESP32-E.

/Arduino/libraries/DFRobot_LedDisplayModule-master/DFRobot_LedDisplayModule.cpp:542:18: error: ISO C++ forbids comparison between pointer and integer [-fpermissive]
if (buf8[0] != "82"){
^~~~

Seems that the ledDisplay library is having a problem?

In short is it possible to interface the Firebeetle2 with the 4-Digital LED Segment Display Module (Red)?

If you guys can help point me in the right direction that would be great.
