fixes: #3446

Hi @tsanislavgatev I saw that "Attention" type is added, the issue mentions also the "Critical" type, is there a reason not to add it or it's planned for different change later on

Hi @ilhan007,
I am not aware of Critical type implementation planned.
But as far as i can see is Critical / Attention which I understand as one of them. And in the explanation given by Marcus it's stated that they need a Warning type of button in brackets asked for one of them both.

Looks good to me @SAP/ui5-webcomponents-topic-b to still review

Yes, the Attention Design is totally sufficient for me :) I was just not sure which name you would prefer in your implementation so I listed both options that are used in UI5 🙂
