Reporting a chat message in ephemeral group channels

It is said in docs that messages in ephemeral group channels are one-time (i.e. Sendbird does not store anything in the database). Still there is a reporting functionality. My question is how are both of these features implemented in the same time? If messages are stored nowhere except the device, there’s no way to figure out if a reported message even exists, we just trust a person who sent the report. So if a person has valid token to my application they can send a simple HTTP request with valid token and fake messages

Hi @Alexei_Sichov - welcome to the Sendbird community!

Can you please provide the reference where you are seeing the reporting functionality for the ephemeral channel? Reporting the messages requires a message ID, and since the message ID doesn’t persist for the ephemeral channel it’s not possible to report.
