I have customized my Google app launcher in several accounts. I have Groups on the app launcher of several accounts, but it's not included in a consumer account created a few months ago. I can't add Groups to the app launcher for this account.
Related thread from the Google Workspace Admin Help community: Google Groups is not in my apps menu and I can't figure out how to add it back in.
On the Google Accounts help center, they included how to customize "the waffle" in the article Use the Google bar.
From the Use the Google bar:
Note: By menu and launcher, the following text refers to "the waffle".
Customize your menu
You can customize the launcher to show your favorite apps at the top. To do this, drag and drop them within the menu.
Note: To customize your menu, make sure you're signed in to your Google Account.
Add more apps
If you'd like to add one you don't see in the list:
- Sign in to your Google Account.
- Select Google apps .
- At the bottom of the menu, select More.
- Drag the Google apps you want to the top of the launcher.
The above doesn't include the whole section content; follow the above link to read the subsection: Add apps that aren't in the "More" menu
What you are calling "the waffle", Google called "the app launcher" in 2015, ref. An additional row of apps and customization coming to the App Launcher.
