How Can Collaborator create New Blog Post?

How do my collaborators (clients) add a new blog post?
When I go in to editor mode, I do not see a “New” button when I go to the blog pages.

Here is my site Read-Only Link: https://preview.webflow.com/preview/old-school-hymnal?utm_medium=preview_link&utm_source=dashboard&utm_content=old-school-hymnal&preview=123029f22089a431f5445f11fd1c5ebb&workflow=preview

Thank you in advance for your help!

I figured it out. My Collections tab was hidden because my screen was too small (or my text was too big due to middle aged eyes! :nerd_face:)
