Just to emphasize one point you made: It appears the first companion planet (160 AU) was originally detected using direct imaging last year (preprint [1] is dated Dec 2019, see sec. 4 for methods). And I guess the second one was announced in OP, making it a multi-planet system. The point of this comment is to note that these 2 planets were originally detected by direct imaging, not by other techniques.
