Hi Team,
I am just learning PX and got a doubt on Engagement Localization :

1.  My doubt is do we need to translate the language and set it up in engagement page using XLIFF file and then use either of those translated languages code in custom attributes or user browser language ?
2. Do we need to manually translate language ?
3. And even after translating language Dont think  any validations happen whether all the language is translated to targeted language ?​​​​​PFB picture where my initial language was in english and i selected targeted language as hindi and i translated it half in Hindi and Half in Telugu which still it accepted.
