To share the right publication URL as Publisher to all your readers:
1. Go to Publications from Side Navigation Menu and click the publication you would like to share
2. Under SHARE, select SHARE LINKS
3. Under SHARE PUBLICATION LINK, click COPY
TIP: The correct Publication URL should contain your (publisher's) username. (As shown in the image, username of publisher is ds_demo).
NOTE: Highlighted URL from below image which does not contain publisher's username is NOT the right publication URL as it is an internal link that's only available to publishers.
