I don't remember seeing this structure/ tense of haber + past participle in the previous lessons.

Could you please point me in the right direction to find where this is taught?
Thank you.
Nevermind, I found this a little later in the B1 section to conjugate haber in present subjunctive, then there is a link in that lesson for the present perfect subjunctive for haber.
