Let's get the elephant-in-clown-makeup in the room out of the way first: Arthur dies at the end of Joker: Folie a Deux, meaning a third movie following the titular clown is very unlikely, if not impossible (unless they decide to go full surreal dream sequence on his deathbed, or a similarly 'out there' premise).

This film is a sequel to the 2019 film, "Joker", the first critically acclaimed award winning R-rated film to gross over $1+ billion.
