App not detected in auto flow and not working great in snap assist mode

HI,
Using KeepassXC on my mac is not working at all with auto flow mode. Whether I add it or not in the Default Floating Window Rules.
If i use the snap assist mode, i kind of work. I can make it fit to my current layout and stick it to another window. But if I want to change the size the whole layout by making a another window bigger, it won't move with it.
