Can't find the "apply theme" button in Styles section

Hello everyone !

I’m on a free plan right now, new on Bubble. I watch some Youtube videos to lear Bubble and I can’t find the “apply theme” button in Styles section.

This section seems to have been redesigned and maybe the “apply theme” button has been removed. I only have the “add style” button.

For a first project on Bubble, apply a theme would have been really helpful.

Thank you very much for your help. Have a great day.
