Unless there is an Youtube page of the blogger (with proper videos and not Short, as Shorts can't be slowed down as well), you can try to download the video from their account to your device (when you click the Share menu there would be a downloading button) and then make it slower using a video editing software like Clipify on your PC. But there is too much hustle tbh, finding a Youtube page with same videos or written materials would probably be faster, unless you want to slow down this specific Instagram video.
Terrible relationship with DIL - am I the problem?
