Hi there; information in the, "Publish" section reads:
Excited to activate your bot? Publish it with a single click.
Yet, from the authoring canvas it takes 3 clicks to access the final, "Publish" button.
1. Left menu > Publish
2. Main section > Publish
3. Popup > Publish
This is just a suggestion to add a true, 1-click Publish option ... perhaps near the header like in Azure's Bot Framework Composer.
