Thanks for your answer.
I understand that there are some problems but I still want to figure it out and maybe solve the problem. I want CTA button to be present in mobile version as I thinks it is important.
Here is the screenshot I took on my first message(https://imgur.com/a/WiIjGr4). I just wanted to show how it looks on mobile device (there is no CTA button), but if you check here (https://imgur.com/a/F69aVFF), you can find black button in the header of the desktop and I do not know whats the problem.
Here is the video I have so you can see that there how I have set it up in Elementor (https://imgur.com/a/zUfyFvD). And here is screenshot from elementor where you can see that I did not hide anything (https://imgur.com/a/PpDuHqz).
So is here even any chance of setting it up? I am a little bit lost.
So if you have any idea how can I put it in mobile header, I would be very thankful.
