This is amazing trick, but unfortunately for me the participants list is long so I cannot keep sending them all meeting invites separately for every week.
As someone suggested earlier, I opened the entire series in edit mode and enabled notes section at the bottom.
Now I maintain by notes under the main meeting notes in loop (it is with the title of meeting without any dates) and keep all notes consolidated there. However, MS Teams does create a new entry with the date and meeting title , every time when this particular meeting starts , with the notes from previous meeting. Which I need to then update quickly as soon as the meeting starts.
So either options are not 100% seamless. :(
