showStore() does not work

I am trying to open the Garmin Connect IQ store for my datafield application:

https://apps.garmin.com/apps/563605a1-b945-469d-b964-eb06a0fb11ad

let iqApp = IQApp(uuid:UUID(uuidString: "4e93029c-304d-45c1-8732-901fb8162887"), store: UUID(), device: selectedDevice)
ConnectIQ.sharedInstance().showStore(for: iqApp)

However, this brings me to a non-existent page. I wonder if the store UUID needs to be set to a specific value but couldn't find anything in the forum or the api docs.

Platform: iOS 18.1.1

Thank you for any help!
