Currently, agents can get the Shareable URL of knowledge base article in Service project > [Knowledge base].

This Shareable URL is formatted like below.

https://<site name>.atlassian.net/servicedesk/customer/kb/view/<page id>

The above URL is located on default help center.
So the breadcrumbs for the article with this URL shows the default help center.

In JSM Premium/Enterprise plan, users can have multiple help center, and they would like to paste the link in customized layout on the help center.
When they add the above shareable link in the created help center, it redirects to default help center and breadcrumbs shows the default help center.
So if they want to add the article link in created help center with created help center's breadcrumbs, they need to update the URL manually.

ex:

https://<site name>.atlassian.net/helpcenter/<help center key>/article/<page id>

It would be better if there is an ability to get the "Shareable URL" with created help center URL.
