Add a spacer to the dock. You can simply drag this spacer just like dragging an app icon. And dragging it out of the Dock would remove it.

There's also a 3rd option to only add a smaller / tiny gap element to the Dock:

defaults write com.apple.dock persistent-apps -array-add '{"tile-type"="small-spacer-tile";}'

Note: all the commands here still work up to macOS 14.5 Sonoma 👍
