I went through a similar process with a different app where I simply couldn't d/l it from Aurora Store. It wouldn't show up on the search or other means. The app was important for my mum, a hearing aid app called 'BeMore'.
So I searched several APK sites, downloaded a few of the BeMore APKs, then uploaded to Virus Total. Some came up with malicious code (file size was a bit suss). But I finally ended up with APK Combo, BeMore from there seemed safe according to Virus Total. I believe 'craftsman myq' is available on that site.
To minimise risk, I also checked file size of each revision of the APK on the site, to see if changed incrementally with each revision. The other thing I did was quickly create a user profile on GOS (what a great feature), installed the APK on that user profile to see if it was behaving badly (to the best of my limited knowledge). Seemed good. Then I installed it on mum's main profile. No dramas. I have had to d/l revised versions of the BeMore app a couple of more times since then from that APK site. And all good. Mum's happy.
