Slack - Post message (V2) -- private channel doesn't show in dropdown menu

I made a flow that uses the Slack - Post message (V2) component. Originally, the component did not show the private channel I needed in the dropdown. I looked at the Slack account of the email I was using and discovered it didn't have access. I invited the user to the channel, it was approved by an admin, and the private channel then showed up in the dropdown and I was able to post to it with the flow.


Then I deleted that Slack - Post message (V2) step and made it again exactly the way I just described, except the private channel wouldn't show in the dropdown. The user definitely has access to the private channel in Slack.


What things can I try / settings to check / etc. to get this private channel to show in the dropdown again? Thanks

Hello! Try clicking the ellipsis (...) in right corner of the action, look at the connections and see if the flow is using a connection from a user that has access to the channel.

I do not have a Slack account to repro this issue, but I was wondering if you see any options to enter custom values in that dropdown. Per the documentation, you may be able to enter a name or ID:
