As mentioned in DM, just a few style notes:

• The input box disappeared. It should have Neutral 100 background with Primary 700 border.
• The input text seems to be aligned to the center, it should be to the left.
• The Cancel button should be Neutral 700 instead of 800 (please check if this needs to be adjusted globally in the entire app).

Unit tests for this component as it seems we missed a few things but I know we're already fixing it on another PR.
