We'd love support adding integrations to Slack guests accounts, but unfortunately, the Slack APIs don't let us do that just yet.
No worries! We have a work around 😎
You can invite Multi-channel and Single-channel guests to Tettra as email users. They'll be able to login to Tettra with an email account as usual and use the slash commands to find pages. You can also set them as guest users in Tettra. Just as guests in Slack only have access to specific channels, guests in Tettra have access to specific categories.
