Feature to add a Channel Calendar using Graph API

Hi everyone

I'm currently working on a Graph API project with my company where we create Teams channel.
After some research, it seems like we can not add a Channel Calendar to a Teams channel (using Graph).
So, is there a possibility for you to add this feature ?
And, what is, actually, the best solution to add a Channel Calendar using Powershell ?

Thank you for your answers,
Alexis
