Breadcrumbs, does the theme allow for them?

I don’t know much about computers. I have installed this theme for my personal blog and I am very happy. It happens that Google console tells me that I have placed breadcrumbs. Since it won’t let me edit the theme I have done it through the file manager, without success. I have also installed a child theme to try to manage it this way, with no success.
My question is if this theme supports breadcrumbs and if you can please tell me a way to do it.
Thank you very much.
