Thank you Akshit @akshitrattan for this PR. I have asked the maintainers about the implementation and it looks like it would be best to make it similar to the FormField class and call getRenderer() https://github.com/joomla/joomla-cms/blob/e2170c8a6224ebb6ed754853de0d5e1b97ba1ce9/libraries/src/Form/FormField.php#L1331 (thank you Fedir @Fedik)

@BrainforgeUK can you give an example code how this should work? wouldn't it be enough to add options to the renderButton option array which can be used for the basePath and the options on FileLayout?
