Hello team. I decided to join your community and found a visual problem. I don't like the look of popups.

For example, like the audio widget on the screen. I would like to make his background with blur effect. I would also like to make the header and footer the same transparency as the body. The search did not lead to any solution. How can I do this?

Very grateful for any advice.
