Rounded Corners on Audio Block

Hi! I'm trying to round the corners of my audio block to match the rounded corners of my buttons. Is there a way of doing this? Thanks!

This worked perfectly, thank you!!!!

Do you also have code to centre-align the text? It's currently left-aligned

Try this:

.sqs-widgets-audio-player * {
  text-align: center !important;
}
