You can easily use it for all the rest but separable verbs, when the particle goes at the end of the sentence, are not managed by LingQ. There is a limitation of highlighting 9 words and usually it is not enough for German.
See this discussion: Why the lingq is limited to 9 words?
In any case, you might find the same verb in many other combinations with the particle attached where you can lingq it as with the other words.
I don’t do it but if I wanted to be more accurate, I would probably use ANKI in combination with LingQ to copy/paste those longer sentences and save them there, or with another method that you prefer.
However, it is also true that if I really wanted to learn some particular separable verbs, I would probably ask ChatGPT to write 20 examples with the combination I want to and improve from there. Maybe save some of those examples as notes in LingQ.
You can easily find workarounds.
