ThisThe article, 'Michael the Great Prince'—Who Is He?, 'Michael the Great Prince'—Who Is He? seems to provide a direct answer to this question: https://wol.jw.org/en/wol/d/r1/lp-e/1984927.
Here's the paragraph that addresses Hebrews chapter 1:
True, the apostle Paul wrote to the Hebrews: “He [Jesus] has become better better than the angels, to the extent that he has inherited a name more more excellent than theirs.” (Hebrews 1:4; Philippians 2:9, 10) However However, this describes his situation after his having been here on earth earth. He was still the archangel and “the beginning of the creation by by God.” (Revelation 3:14) But he became better than the angels. The ‘more ‘more excellent name’ or position is something he did not possess before before coming to earth. (These scriptures contradict the Trinitarian concept concept that the Son is and always has been equal in every way to the Father Father.)
I suppose this could be something like an "official" stance.
