Anything in the logs? Have you invited the app to the channel?

[Lovee2412]

Yes invited
Is mandate to select Custom slack app bot user?
If i select this it will be problematic for others channel notification

[timja]

there's more features in the bot users so it is recommended.

The 'legacy' one has not been updated by Slack in a long time

[Lovee2412]

if it is set then it will impact the flow which use legacy app?

[timja]

not if you leave botUser off globally and only enable it in the jobs you need it.

[Lovee2412]

how to set globally off for botUser and enable in job level
thank you very much
