      equals: "" 
      commands: "" #optional
  authorized:

      equals: "" 

Use %player% for the "commands: "

EXAMPLE WITH FACTIONUUID

conditions:
    my-first-conditions:
      placeholder: "%factionsuuid_faction_territory_name%"
      equals: "§2Wilderness" 

Here the player can only fly on his claim.

Make sure your placeholder return the value of "equals:"

Now, the problem here is that the player will only be able to fly in his claim only. Fortunately,, the authorized section is there to counter this.

conditions:
    my-first-conditions:
      placeholder: "%factionsuuid_faction_territory_name%"
      equals: "§2Wilderness" 
  authorized:
    my-first-conditions:
      placeholder: "%worldguard_region_name%"
      equals: "spawn" 

With this config, now player can fly in the region "spawn".

EXAMPLE WITH LANDS
