How to disable scroll to next slide in xaringan + slidy output in Rmardown

[XoliloX]

Dear all,

I write to you because I've tried different methods to disable the "scroll to next slide behaviour" with the mouse (because this enabled, you can't zoom in a map). I've tried literally dozens of CSS and HTML modifications (in the Rmarkdown document, in a separate file) but none worked. Would you have any recommandation on how to best do this ?

My header has the following informaiton:

output: xaringan::moon_reader: css: "xaringan-themer.css" nature: slideNumberFormat: '%current%' highlightStyle: github highlightLines: yes ratio: '16:9' countIncrementalSlides: yes

In advance, thanks a lot for your answer!
