Need help removing this - Dont know the name

I think there are to many stuff showing which page i’m on. I would like to remove the part i marked.

Hello there,

I hope you are doing well today.

You can use the following CSS code to remove this section by going to Appearance > Customize > Additional CSS and pasting it there.

/*Remove Header callout*/
.header-callout {
    display: none;

Best Regards,
