Align advert in widget in centre

Hi. I want the images used in adverts in my sidebar widget to be aligned in the centre of the widget. Currently, they are aligned to the left of the widget, which doesn’t look correct.

The current advert is located as the last item in my sidebar (see link above).

The advert code is currently:
<a href="https://poddoc.co.uk/"><img src="%asset%" /></a>

How would I best centre the advertising image within the widget container?
