Cant hide banner button from just main page

my custom css to delete the banner button in the main page doesnt work, what am i doing wrong? its the right body id and the right class for the button.../ the button isn't live on the website url btw

* Hide the button to schedule a call from main page banner */
 

#collection-6008977b07d3d855bb77b2c8 .header-actions.header-actions--right {
display: none !important;
}

Add this to the home page settings -> advanced -> header code injection:

<style>
.header-actions.header-actions--right {
  display: none;
}
</style>
