But keep current selection.
*Tips
Every element of the add-on UI has a tooltip, so if you don’t know what something does just hover your mouse cursor over it.
If you want to use this tools frequently I recommended assigning some “Shortcut” to operator that you want to assign for,
to do this, just Right-click on the button that you want to assign.
If you have familiar enough on this add-on, you may hide that N panel in add-on preferences and access the add-on through shortcut you have assigned or pie menu
