No, 3rd party tools are not supported and shouldn't be. They were inadvertently since SE looks at clear data for balance but I think they've gotten smarter now.

Balancing around simulators and automarker or aoe showing boss mod plugins just makes the game less fun all around for anyone playing vanilla. Never, it should never be done and anyone who uses these should know they are throwing off the balance of the fights on purpose so they can get easier clears.

If it feels too easy it's 100% on them for installing tools that trivialize mechanics and parts of the difficulty.
