Discord has upgraded its embed system and introduced new components, giving you even more creative possibilities!

Place buttons inside or above your embeds.
Add selection menus inside or above your embeds.
Use spoilers directly within embeds.
Insert separators with customizable spacing (level 1 or 2) to keep things clean and organized.
