Hide Brave Shield Lion Icon?

Description of the issue: There’s always a brave shield lion icon in the omni box which is honestly kinda too outstanding, it would look better if it can be hidden.
How can this issue be reproduced?

  1. Install Brave
  2. Open a non-internal website
  3. Check the right edge omni box

Expected result: Icons there should have designs that are more consistent with all the other icons.

Brave Version( check About Brave): 0.69.135
