I made all the changes but struglled with 4
The CSS appears on the DOM appears to be the following:
.elementor-13706 .elementor-element.elementor-element-665a47c .elementor-cta__button { color: var( --e-global-color-secondary ); border-color: var( --e-global-color-secondary ); }

Which doesn't seem to exit in the codebase. I will create a PR to review my changes and get some input on where the feedback cta button is.
