Creating Amazon Lex V2 bot versions for Amazon Chime SDK messaging

When you create an Amazon Lex V2 Bot, you only create a draft version. The draft is a working copy of the bot that you can update. By default, the draft version is associated with an alias called TestBotAlias, and you should only use the draft bot for manual testing.

After you finish dialog modeling and building the draft bot, you create one or more versions, numbered snapshots of the draft Lex bot. Versions allow you to control the implementation that your client applications use. For example, you can publish versions for use in different parts of your workflow, such as development, beta deployment, and production.
