[2023] Is there any updates on the next Essence Emporium or any other event where I can spend my BE?

I am now nearing 300k BE, and have nothing to spend it for. Has Riot confirmed when they will bring back the Essence Eporium? Blue Essence just seems so worthless when you have all the champs. They should least implement an OE converter to have some use for them, because I could definitely use more of those.
