permissions needed for microsoft graph planner tasks?

Question

I am using Microsoft Graph explorer, and enabled permissions include: User.ReadWrite, User.ReadBasic.All, Tasks.Read.Shared, Tasks.ReadWrite, Files.ReadWrite.All, etc.
Not: Group.Read.All (because Admin).

In the explorer I am logged in to my Office 365 account.
E.g. https://graph.microsoft.com/v1.0/me/ works fine.

I am not able to use any of the Planner endpoints. E.g.: https://graph.microsoft.com/beta/me/planner/tasks

gives 403: You do not have the required permissions to access this item.
The same for e.g. https://graph.microsoft.com/beta/planner/plans/<id>/tasks

Tried both beta and v1.0.
What additional permissions are needed?

PS. Tried it with two Office 365 accounts.
The Planner endpoints work fine with the sample account (=when not logged in).

PPS. Sounds similar to this one, but in my case I have not seen a successful response yet.

The docs state you need Group.Read.All. I get that requiring admin consent for this isn't great, but it looks like for now that's the answer. I'd suggest voting up this UserVoice post.
