To connect multiple bots to different channels, you simply need to create more bots (as long as you have enough available in your plan).
Once you have created all the different bots you'd like, and trained them on your knowledge, you can then follow the prompts via Integrations > Slack to install the Slack app in your Slack workspace.
Once it's connected, you can then click on the Slack integration on the left sidebar in your eesel dashboard. Here, you can specify which channels the bot is operating within.
Simply do this for each of your bots and @ mention eesel inside your Slack channels to chat with it.
