Custom Sidebar for Single Posts (all posts)

Hi there;
I have a question about creating custom sidebar. I want to create custom sidebar for “single posts” (all single posts will have same sidebar). Single Posts will have different widgets at the sidebar than the Blog Archive sidebar.

Custom Sidebar for Single posts (for all posts) and I will place it to the rightsidebar.

Can you please give me a code snippet for this? I haven’t found it at the knowledgebase of the OceanWP website.

Thanks in Advance.
