Deleting messages from private channel

[MovGP0]

I have a private channel with an misbehaving bot that filled up the messages. I tried the following:

$token = 'xoxp-.......';
get-slackchannel -token $token -name "privatechannelname" | Get-SlackHistory -Count 1000 | Remove-SlackMessage

unfortunately, this only works with public channels. Is there any way to delete messages from a private channel?

I guess the support for OAuth App Credentials might be required, because the credentials of the bot have the proper access rights.

It seems that when deleting from private channels you need to specify the ChannelID and not the Channel name. The piplined input contains only the channel name. The Remove-SlackMessage help file shows adding in channel ID info for such a situation:

Get-SlackChannel -name "TargetChannel" |
                Get-SlackHistory -Count 1000 |
                Where-Object Username -match "MalfunctioningBot" |
                Remove-SlackMessage -ChannelID "C5H8XBUMV"

However, that doesn't seem to be currently working. I made a fix here https://github.com/RamblingCookieMonster/PSSlack/pull/104 that I believe addresses the issue and will allow you to specify a ChannelID for Remove-SlackMessage.
