Hi Xoxe ,
Just like @JonasT explained, this is possible with Page Rules.
With Page Rules, you can specify the page you don't want the button to appear in. You can also specify which user roles you would like to show the button to.
For example, I don't want my button to appear on the contact page of my site. I also don't want it to appear for users with the role, editor.
This is how I would do that using page rules:
As you can see in the video, the button only disappears on the contact page.
Let me know if this was clear enough. 😄
