• in medium size the icon size should be 20px, not 24px

• the close button is always neutral, it should have the sentiment of the Alert
• the close button is bigger than on Figma but on Figma it's not a button so I'm not sure how to implement that

[jsulpis]

the icon is too high, you can add a margin-top of 2px like on the small size
