The And and But keywords that are valid in Gherkin are not exposed in Cucumber's TypeScript API. Until recently, they were incorrectly exposed in cypress-cucumber-preprocessor (which I assume you are using), but this has been removed in 13.0.0

More details in badeball/cypress-cucumber-preprocessor#821

Thanks for your contribution, but we won't be adding this since using And and But in step definitions is discouraged and not even supported in Cucumber and the latest cypress-cucumber-preprocessor.

Is the intention that this plugin only be used with official cucumber libraries or provide matching for the gherkin language?

I'm using jest-cucumber which provides methods (even if just syntactic sugar) for the whole gherkin vocabulary including And/But. In jest having contextual tests makes sense since they are defined in a context with other tests.
