Describe the issue you are experiencing

When navigating to Settings -> Devices And Services -> Integrations, a list of discovered devices is shown at the top of the page.

When pressing the ADD button on the discovered items, some of the Add menus that pop up have the options of X or Submit. However, some of the Add menus only have the Submit button and do not have an X button. This requires the user to refresh the page if they do not want to continue configuring a discovered device and they happened to press the Add button accidentally.

For example, with a discovered Brother Printer, when clicking Add, I have the options of X or Submit.

With a discovered Samsung TV, when clicking Add, I only have the option of Submit. I do not have an X button for this device's Add menu.

Describe the behavior you expected

I would expect all of the menus that pop up after pressing Add on a discovered device to have the option of X or Submit.
