Language switch button in footer

Site URL: https://qerko.com

Hi,

we would like to have our page qerko.com in 2 languages - default is Czech, the other one would be English. We use Squarespace 7.1.

I have read the multilingual instruction provided by Squarespace, however we would prefer to have just a button (flag image) somewhere in footer that would switch the language of the site. 

Is there a way, how to do it? I am not that skilled in CSS so I can’t figure it out myself, unfortunately. 
 

Thanks, 

Andrea

I think you can use WeGlot, I remember they has option to place switch button in footer.
