Power Virtual Agent Bots as Skills for an Azure Bot

Hi,

We have an Azure Bot deployed and are exploring the possibility of using a PVA Bot as a skill for the Azure Bot.  From https://learn.microsoft.com/en-us/power-virtual-agents/advanced-use-pva-as-a-skill#add-your-bot-framework-bot-to-the-allowlist-for-your-power-virtual-agents-bot, we have read that we can add a PVA Bot to a Bot created via the BotFrameworkComposer as a skill.  However, we did not find any documentation on how we can accomplish the same using code.

Our Azure Bot is written in NodeJS.  We have a skill dialog bot that is currently connected to the root bot using NodeJS.  Is it possible to have our NodeJS root bot talk to a PVA Bot?  

Thank You
