Design a virtual meeting grid layout featuring nine participants arranged in three rows. The top row displays three participants, the middle row has three, and the bottom row contains three. 

- Change background settings: Use varied abstract or nature-themed backgrounds instead of a recognizable cityscape.
- Alter participant attire: Switch to casual wear to create a more relaxed atmosphere.
- Adjust video framing: Make sure all participants’ faces are clearly visible, with a soft focus on the background.
- Remove any brand logos or names but keep name tags for each participant.
- Enhance the color scheme: Opt for softer pastel colors for the video borders and grid lines to create a welcoming vibe.
- Include a chat or interaction button at the bottom right, but change the text to "Join Discussion" instead of "Ask to unmute." 

The overall aim is to maintain a professional yet approachable feel for a virtual gathering.
