What would you use this icon for?

When we have a groups we can:

• use account-multiple to identify that,
• use account-multiple-remove to indicate delete option,
• use account-multiple-plus do indicate add option,

No icon to identify edit option

Give us an example of what this icon might look like.

Combination of account-multiple and account-multiple-outline with account-edit or account-edit-outline
