Hi @tmaroschik , thanks for PR, can you add an example in README.md?

[moritz-ngo]

Here's a simple example, when using web-vision/deepltranslate-core

label: 'DeepL Translate'

custom_options:
    deepltranslate:
        - translateAllowed

I've tested this PR and it work's like expected.

@tmaroschik it would be gread if you could add tests as well
