Slack: "Reply in Channel" click gives the error: "intercom: We couldn't find the user who started this conversation in Intercom." when the chat was initiated via intercom.
We have 2 support workflows, workflow-1 works fine but workflow-2 doesn't.
WORKFLOW-1 (Works): Our app users send a message via in-app intercom messenger and it gets to our slack channel where the support engineer can click on "Reply in channel" to start a conversation. ALL GOOD WITH THIS WORKFLOW
WORKFLOW-2 (Works partially): We want to send a new message (not reply) to a particular user, preemptively (without that user ever having send us a message first). We send this message via intercom dashboard... but then we want to continue any conversation on our integrated slack channel...
So what we do next is this:
1) After sending this message to the user, we assign this conversation to our "Support" intercom team.
2) Only after this assignment, it pops up a message on our slack integration channel, BUT if we then try to hit "Reply in channel" to this conversation, we get a message saying : "Intercom APP: We couldn't find the user who started this conversation in Intercom." and we can't continue this chat.
