I had no idea what you meant with "swipe 3 fingers upwards and one downward", but the image and description at https://support.apple.com/en-us/HT204895 made it much more clear.
OTOH, more than one mouse button would be "confusing".
I have a 90% success rate with my totally different approach-
put four fingers in the center of the trackpad- not touching each other, but very close. then naturally spread them apart.

F11 does it
I've been trying to get the show desktop gesture on my mac right for years. You know, the one that "windows-D" was doing so loyaly for ages.
My habit is to arbitrarily swipe as many fingers as I can find available from center of trackpad outwards. It used to take me ~10 trials to get it right.
And now, enlightened by this random thread, I suddenly figured out I actually need to swipe 3 fingers upwards and one downwards simultaneously. This is the greatest Epiphany HN had given me since https://news.ycombinator.com/item?id=13651148
