Dim Method Plugin Change Button not showing up

Hello, I am performing on my tailor made concept and I tried using to put in the WordPress Darkish Mode plugin. I have activated it and set the **Allow Frontend Darkmode** and **Exhibit Floating Swap** effectively. I opted for the floating switch to surface in the base left.

However, the change isn’t going to show up. I know the precise dim manner performs – I am able to swap it on and off with ctrl + alt + d. For no matter what cause, the button just doesn’t surface for me. Could it be due to the fact I’m utilizing a custom made theme?

Has any one arrive across this, and if so, would you have any information?

Many thanks in advance.
