Ok. So you already have one ap group with all those profiles. Apply the mesh profiles referenced above to this group.
Select one ap from the list and provision it as a mesh portal. This is the ap that will accept the mesh ap's traffic to dump it on your LAN.
Next select another AP as the mesh point. Once done, it will reboot and try to be a mesh ap. Simply deploy it where needed. This ap should form a mesh link to the portal and also serve clients.
