Hotspot

Hello,
I have a problem this the hot spot function.
I need to use my website with that function on a big touchscreen in a showroom.
The problem is I can only choose between “display at hover” or “display all the time” (I’m translating from french might be not exactly the good wording).
The thing is I need to display the lightboxes with a click but its not possible.
It’s working properly on mobile (with click) if I choose not to display it below the hot spot image.
The problem is the website does not detect my touchscreen as mobile (normal) but I would like it to do so.
Do you have a solution for me?
Thanks
BR
