Importing a file gives a 400 Bad Request error

Dialog without footer and header inconsistent, there is no way to close it.

When there is an error and the user cannot click on the primary button, there should be a tooltip on the button so the user understands why they cannot click on it.
The required input field should have an error message bellow.

The Choose File Link has smaller typography than the rest of the copy, also it should be blue (like in image and file)

Info icon has weird aligning.

We are showing the same info in the preview and the info button, let’s remove the info button.
