Floating button issue

[muhammad_haroon]

I'm encountering an issue where, when I use Shopify's Dawn theme version 9.0.0, my floating button appears at the bottom left.

But when I use Shopify's Dawn theme version 10.0.0 or 12.0.0, or the latest version, the floating button doesn't appear at the bottom left.

Please tell me a solution so that, regardless of whether it's an old or latest version, the position of my floating button doesn't get messed up and it always appears at the bottom left.
On the Dawn theme version 9.0.0, my floating button appears at the bottom left, which is exactly where I want it to be. However, when I use any version other than 9.0.0, the button doesn't show at the bottom left.
