I own a Toyota Avensis 2004 1.6 petrol, whenever I turn AC on and I drive a high gear with low rpm or even low gear with low rpm it makes a clicking noise as shown in the video below, what could be the cause of this or what should I try to identify the problem?

Can you do another video with the hood open, and if possible the AC compressor clutch while it is doing this?

If is does not do this in park or neutral, then yes, I am with CORROLLAGUY1.

If it makes the noise when parked, brakes on, in D, you might can narrow down what’s causing it using a lengh of old garden hose as a stethoscope. Probe around int he engine compartment, maybe you can narrow it down. No way to tell via the internet, but my wild-guess speculation is the serpentine belt tensioner is failing. After that the AC compressor.
