<Todo initialId=xx explanation

[Ofer-Gal]

I created a dashboard for users with the intention that the user will see his own normal tasks and also in a shared list named "DPC Waiting answers"
so the component has :

<Todo readOnly />
<Todo readOnly initialId='AQMkAGU1N2IzNzQzLWYxOTAtNDVhZC1hMzUwLTA5NDYxMjgxOWE1ZAAuAAADShAE-RtDyUmHgJPRQmNeGwEAqJV_CoHTGUquHi0v_ME1WAAC6aNGKgAAAA==' />

On my dashboard I see

On other user's dashboard he sees

Why does it show the regular Tasks twice?

I ran graph explorer as that user https://graph.microsoft.com/v1.0/me/todo/lists and found out that the ID of "DPC Waiting answers" for him is not the same as mine.(the id I gave initialId )
If each user gets a different ID for the same shared list, how can I populate the <Todo component in the web part?
I did not see an option to use the "displayName"

Is there a way to show all the Tasks that "Assigned to me" from all the lists at once regardless of list?

Thank you
