Auto-Translate opcion ?

Hello mates,

I buy wordpress theme that is very hard to translate.
Theme is on English and i need web site on Serbian,Bosnian,Italian…

So, is possible when someone vist my site,this plugin automatic translate my theme to Serbian,and when visitor click on other language to translate theme to this language.

for example:
When visitor vist my site,site automatic translate from English to Serbian,and if visitor than click on thih button; https://prntscr.com/5olbn6 and chose Bosnian flag,site automatic translate from Serbian to Bosnian.

Sorry for my really bad english
