[Theme: Creativix] a "go to next slide" function in slideshow

hi there
i’m using creativix template, i love it so much : https://intheloop.fr/
i changed the slideshow to remove the slidenavigation, i didn’t like it that way : the slidenavigation (original one) with the mini thumb allowed only to move the thumb, not the slide.

i just want to add arrows on the left and the right of my slideshow, that would go to next slide of to previous slide.

does anyone kwon if it’s possible ? is there somewhere so kind of “move to next slide” that i can trigger with a button ?

thanks a lot
