Additional context: I want to replicate this kind of input/button relationship.
https://getbootstrap.com/docs/5.3/forms/input-group/#button-addons

Since the web-components are not allowing you to put a button right next to the input, I have tried putting then into the slots. But it looks kinda misplaced here. Is there any way to replicate the same styling? This could be useful for specific UI like search windows. For example:

Even more context:

Perhaps it might be a good idea to at start and end slots to the fluent-field component
https://storybooks.fluentui.dev/web-components/?path=/docs/components-field--docs

You could add the buttons the before and or after the input and you would have full support with message and label as well.
