How to add a channel to a team during a ms teams bot process

I have a JavaScript Microsoft Teams bot application. It is a notification bot. Users install the app in a team. The team's users can start a conversation with the app in any of the channels, and the app will notify them in that conversation by posting the notification to the channel where the conversation started. Sometimes, it is necessary for the app to add a new channel to the team. This bot is built on TeamsFX. My question is, is there any way to add a new channel to the team using TeamsFX or the Teams JavaScript SDK, or should I focus on adding code using the Microsoft Graph client?
