Expression cannot be used as a function

[fatburg3r]

I tried compiling the example sketch provided in the library using the Arduino IDE, but I got the following error. I'm using an Ardunio Nano 33 BLE. Any idea why this is happening?

Arduino: 1.8.19 (Windows Store 1.8.57.0) (Windows 10), Board: "Arduino Nano 33 BLE"
