Eventually in Darkseid War, the ring takes over Jessica completely for a while, until she takes control back and saves the Flash from the Black Racer, who ends up killing Volthoom and freeing Jessica, she becomes a Green Lantern right after.
I left out some details but I think that's pretty much it.
