Help me with identifying steps for MS team with nodeJS backend

Question

Hello everyone,
I hope you all are fine.
I am the developer of www.stackby.com and we are using nodeJS as our backend. Now, we want to provide a service that if you provide MS team id or some key then we can be able to retrieve team data, channel data, or members data according to need.
However, I am new to this and this is the first time, I am leading a team and I want to succeed no matter what. So, please someone will help me by simplifying the steps thus I can grasp them and make my team working on that one.
If you provide me this help, I will be grateful forever.
Thanks

If you want to use MS Graph to get the team,channel and other details first you need to have an access token and later use that access token in headers while making a graph call. You can start from here.
