To make the bot available from Microsoft Teams and from the company's internet website, you need to configure the channels for the bot. Power Virtual Agents uses channels to connect the bot to different communication platforms such as Microsoft Teams, Skype, Facebook, and more. By configuring the appropriate channels for the bot, you can make it available on those platforms and allow users to interact with the bot from those locations.
You can configure channels by going to the Power Virtual Agents portal, and then select the bot you want to configure. Then select the "Channels" tab, where you can add the channels which you want the bot to be available on.
