WordPress Get Posts With Filter Option

Hi, im using a custom query to get a custom post type and with a certain taxonomy. I can retrieve the results ok but im using a search filter with the plugin called WP Search And Filter Pro’ ( ‘https://www.designsandcode.com/wordpress-plugins/search-filter-pro/
)

They mention that if i use a archive page for my custom post type the filter wont work. just on the standard loop posts.

Basically i have a archive page for my custom post type where i return the results based on a certain taxonomy as this is dynamic based on the type of user logged in. But i need a search filter which can further filter down from there.

Any advise would be greatly appreciated. Can i pre get posts somehow so i can use the standard post loop?
