Custom Names don't work with webhook messages
When we enabled indexing, all messages first appeared anonymized (all with the same name and profile picture) - also we didn't have anonymization enabled for that channel.
Now when we had more messages coming in, the bot recognized the webhook as consented (using forum channel consent) and used the same name for all messages (it just used one of the names of the authors).
We are using custom names for every message sent with this webhook.
