It should be possible with a Press button in web page action, if you capture the element correctly, and also make your flow click on the field to make the option visible before attempting to press on it.
Can you try to capture it and share a screenshot of the selector?
Also, can you try right-clicking it on the browser itself and selecting "Inspect", so you can see the element in the browser's developer tools? And share a screenshot of that, too.
