Currently, Essentials can deploy Einstein Bot metadata but it will deploy all the versions of a Bot to the target org.
The BotVersion metadata is used to deploy a specific version of a Bot. This functionality is working, but Essentials has an issue listing them in the "Add Components" tab. We will fix this and deploy to production mid this week.
For now - the workaround is to click on More > Import Component Selections and manually enter the Bot version. For example, if I want to deploy v2 of a Bot named "CD_Bot", then I would need to enter BotVersion/CD_Bot.v2 in the Import Component Selections text box. See screenshot below.
