French forms omit the subject. Use j’ before a vowel sound. Vous is polite singular or plural “you”; on often means “we,” or the general “one.” English wording depends on the context: passé composé can also use “have,” and the imperfect can describe an ongoing action. Subjunctive translations here follow “it is possible that.”
