Unable to switch GTK and shell themes synchronously when switching day/night themes

running at manjaro linux 6.4.91
gnome version:44.3
I tried to use extention(User Theme X) but it doesn"t work completely.
please tell me how to fix it

Manjaro heavily modifies GNOME, to the point where I think you’d be better off asking in their forums instead

I have immersive-dark-mode for my use case (GTK3 & Cursor theme). It is a very small and simple Python script. You can modify it to fit your needs.
