Can I ask how to activate the badge icon as shown below? I am struggling to find it in the 4.5 ACP, I can see 'Group Icon' in the ACP Member Group Setting but this badge looks like a different element.

That’s shown automatically for moderator accounts.

Thank you for clarification. I have noticed another badge here: 'recently joined' how is it defined (e.g. showing 3 months since registration) and can it be adjusted in ACP anywhere? Are there any other badges we should be aware of?

The recently joined badge is shown for members which joined in the last 30 days
