Sidebar for blog posts

Need to add widgets to the Blog posts sidebar pages, is there a setting to add sidebars? thank you

Posts don’t have a sidebar by default (the content is centered), but it’s possible with customizations, if you’re familiar with the theme customization basics please try overriding the single.php file via a child theme.

Could I suggest on a future theme update you add the option to have sidebars? Its a negative not being able to add banners to out blog posts
