Translate text in Chrome Extension using undocumented API

The Google Dictionary Chrome extension makes requests like this to do translations:

https://clients5.google.com/translate_a/t?client=dict-chrome-ex&sl=en&tl=ru&q=text

We can do the same (for the moment at least):

fetch(
  "https://clients5.google.com/translate_a/t?client=dict-chrome-ex&sl=en&tl=ru&q=text"
).then(function(res) {
  res.text().then(function(r) {
    let code = ''+r;
    log(code)
  })
})

Result:

        "trans": "текст",
        "orig": "text",
        "backend": 2

To convert it to a js object just call JSON.parse on it! ]
