Hi there, @MICHEL_A3A 
A huge thank you for your interest in our app!
I am afraid this feature won’t be released by the end of this year. I am really sorry!
We completely understand your desire to get this feature as soon as possible and how helpful it would be for some users.
But the thing is that we prioritize request based on their complexity and popularity. Right now, we have a lot of requests with the higher priority level and our devs are working on them.
However, we are not going to abandon this idea and, hopefully, we’ll be able to consider it in 2025. If anything changes, we’ll update you in this thread - Event Calendar Subscription
