I'm afraid your requirement is not possible at the moment, but if you want to highlight show some content in your workspace, As a workaround, you can try to package reports, dashboards into an app and then share the app.
This article is about how to better collaborate in the workspace：
If colleagues need to keep the report up to date, or need access to all the content in the workspace, add them to the workspace as Members or Contributors.
If colleagues just need to view the content in the workspace, add them as Viewers.
If colleagues just need to see that report and not all the content in the workspace, you can share the report via link or grant them direct access.
If the report is better consumed with related reports or dashboards that you need to distribute to many colleagues, then publishing anappis likely the best choice.
If you want to use the same dataset to create a report, New workspace supports shared datasets, you can use the dataset in New workspace A to create a report in New workspace B. Make sure your tenant has enabled the option "Use datasets across workspaces" in admin portal.
Hope it helps,
