An efficient translation tool, that can be used to translate any type of PDF (Editable and Non-Editable) from and to any language

• The next step is to obtain the JSON file containing credentials of the service account created, this can be followed to do the same : https://www.youtube.com/watch?v=rWcLDax-VmM
