Just my thoughts, but it is a SMR. I think that inclusion adds character. Can’t really tell from pics, but if inclusion is deep, fill with wood patch If not, finish as usual, and be happy. Will look great.
i agree with Tizzy, but that is just one guy's opinion, and doubtless well worth what yo paid ... either way, it's gonna look really cool when done ...
Really, for 99.9% of people, either colored epoxy or the dark brown CA glue is the best fix for something this size or smaller. It's about a 5 minute job and will look pretty darn good when finished.
