Change Label Name with script

Change Label Name with script

Hello everyone,

Is there a way to change the Label Name with script??

I would like to have the option to change the language of the application, so I was thinking if this could be done?

Besides that, is there a way to know the user that is Sign In? Because I could automate the language function if the principal question were responded.

Thank you very much for your help and sorry for my grammar English errors.
