Always show previous/next button in Query Loop Pagination

The WordPress pagination defaults to not outputting a previous or next button/text if there is no previous or next post/page to link to.

How could I add or mimic an inactive button or text to the GB Query Loop pagination in order to keep the pagination buttons in the same place, even if there is no previous or next post/page to link to?

I’m using svg arrow icons for the previous and next buttons and would like to show an inactive/greyed out icon if it’s not possible to click further in that direction. Keeping the navigational elements in place is my main goal.

Thanks for your input on this in advance!

Kind regards,
Sebastian
