2 different PWM frequencies required, but ledcAttachChannel was not declared in this scope

I need two different frequencies for my project, 4KHz and 20KHz. The use of: ledcAttach(2, 4000,8); ledcWrite(2, 127); ledcAttach(10, 20000,8); ledcWrite(10, 127); deliver on both channels/Pins 20KHz; The use of: ledcAttach(10, 20000,8); ledcWrite(10, 127); ledcAttach(2, 4000,8); ledcWrite(2, 127); ...
