You can order translations from your WordPress in two ways. Either go to the content you want to translate and order the language you want from the "Languages" box (circled red in the screenshot below):
If you have more than one page or product you want to translate, you can order translations as a batch from the "Bulk actions" box in the "Pages", "Products", or "Posts". Choose the content you want to translate, choose "Order translation" from the "Bulk actions" box, and click "Apply". Please note that you can only bulk order translations from the same language.
Once you have selected pages, posts, or products to be translated you can choose in more detail what content will be pushed to translation. On the lower-left corner, you can choose what language you want to translate into:
After clicking "Next" you can choose if you want to use machine translation or professional translations with proofreading. Choose the desired level and click "Order Translation". You will get a confirmation email to your inbox as well as verification once the translations are ready.
