Gnome Shell's multi-touch gestures are only meant to work on touchpads.
They do not exist on touch screens. Although your use case of trying to
scroll a web page is completely unrelated to that...

Title:
Multitouch gestures do not work on touchscreen in 20.04 X session
Status in gnome-shell package in Ubuntu:
Invalid
Bug description:
Installed the latest 20.04 yesterday. Completely new install.
All works fine except fingerprint reader (ok) and multitouch gestures
on the touchscreen of my laptop. Mind that multi-touch gestures do
work as intended on the touchpad.
Expected:
It should be easy to scroll a webpage using fingers on the touchscreen (in
tablet mode for example).
Observation:
Using touch on the touchscreen, text is selected and the webpage does not
scroll.
