I am trying to figure out how to officially run a Store Championship Event at our Saturday Event, does anyone know how we do that?

I am fully familiar with the Chainbound Events and have successfully run multiple but the GEM doesn't seem to have an option for the new Store Championship Event and all of our players are interested in earning the extra Aember shards offered through the new Event type. Also, anyone know how often this new event type can be run?

I have already scoured the website for retailer info on this subject but come up empty handed and don't know where else to go. I have also scoured the GEM to try to find answers to no avail. Any official help on this topic would be highly appreciated.

No official help, but have you updated GEM before doing your research there? I know that the extra shard chainbounds only worked on the then lastest version for example.
