My example is for Windows batch file. I think (but I'm not sure) that in 
Linux you must encapsulate the whole filtergraph in " " double quotes:

ffmpeg -i 20220421_163910-meet.mp4 -i image_with_clut-meet-edited-clut.png -filter_complex "[0]eq=brightness=0.06[a];[a][1]haldclut" -y 20220421_163910-meet-edited.mp4
