Best solution to create a bot that joins a Teams online meeting

Question

I need advice on a solution to program a bot that joins an online meeting at a certain time. The online meeting is already created with the Graph API, i.e. the join data etc. are all available. The bot also does not have to stream the video/audio but should simply enter the meeting once at the beginning, as the meeting is conducted by two people outside my organization/AzureAD.
This is required so that the recording of the meeting can then be saved in my tenant. It is not possible to add the people to my AzureAD or add them as guests. So the question is: What is the easiest and fastest way to implement this (if possible, I would prefer to program this with Python)?
