Step 6: Add calendar.readonly Scope (Navigate Back)

Problem

You created the OAuth consent screen but need to go back and add the scope.

How to Find the Scopes Page

Method 1: From OAuth Consent Screen (Easiest)

1. In Google Cloud Console, make sure you're in project hoffmann-icarus
2. Left sidebar: "APIs & Services" → "OAuth consent screen"
3. You should see your app "Icarus Family Assistant" listed
4. Click on "Icarus Family Assistant" (or the edit/pencil icon)
5. You'll be back in the setup wizard
6. Click "Edit" next to "Scopes" (or click "Scopes" in the top tabs)
7. Click "Add or Remove Scopes"
8. Filter box: type "calendar.readonly"
9. Check the box for: https://www.googleapis.com/auth/calendar.readonly
10. Click "Update"
11. Click "Save and Continue"

Method 2: If You See the Full Wizard

1. You might be on the "App information" step
2. Look at the top of the page — there are tabs/steps:
   - App information ← You might be here
   - Scopes ← Click this
   - Test users
3. Click "Scopes"
4. Click "Add or Remove Scopes"
5. Filter: type "calendar.readonly"
6. Check the box for https://www.googleapis.com/auth/calendar.readonly
7. Click "Update"
8. Click "Save and Continue"

What You Should See on Scopes Page

The scopes table should show:

AND NOTHING ELSE. If you see calendar (without .readonly), that's wrong — remove it.

Screenshot Description (What to Look For)

After clicking "Add or Remove Scopes":
- A panel slides out from the right
- Filter box at the top — type "calendar.readonly"
- Table shows matching scopes:
- Row: https://www.googleapis.com/auth/calendar.readonly
- Description: "See and download any calendar you can access using your Google Calendar"
- Checkbox: ☐ (unchecked)
- Check the checkbox
- Click "Update" at bottom
- Back on main scopes page, click "Save and Continue"

Still Can't Find It?

Alternative path:
1. Left sidebar: "IAM & Admin" → "Settings"
2. Or search the top search bar for "OAuth" and select "OAuth consent screen"

If the scopes tab is grayed out:
- You might need to complete "App information" first
- Fill in app name, user support email, developer contact
- Click "Save and Continue"
- Then scopes tab should be clickable

After This

Once calendar.readonly is added:
1. Click through to "Test users" tab
2. Add hoffmann.family.manager@gmail.com as test user
3. Click "Save and Continue"
4. Then proceed to Step 4 (Create Credentials)
