Could you add a feature to showcase things in your inventory?
I'm not sure how difficult it would be but I'm thinking

• what you're wearing,
• hotbar,
• inventory
• ender chest
• tab

it could just be like images like this below, which would make it a lot more interactive with the discord, I think it could be possible with an embed but not sure.

How would this work?

Like what would you do to get it to show in discord?

From a development standpoint, it's not as easy as it sounds. Image generation is not cheap on server resources, and will definitely be a problem for most people using the mod, since they are using shared hosting
