Slack bridge - is there a way to get a working bridge without "Slack App (Classic)" ?

[MrJohanssons]

Hi

We have a group we would like to chat with that uses Slack. We suggested that we use matterbridge to communicate between Mattermost <----> Slack. But they came back and told us that their org doesn't allow classic apps since they don't have granular permissions.

Is there any other way to setup the Slack bot?

have same requirement (cannot even create Classic app now as I understand) but for integration with Nextcloud
