To access the contents of an existing Dataset that is not in your project, mount the target Dataset in your project.
From the navigation pane, click Datasets, then click Mount Shared Dataset.
Click Dataset to Mount to see a list of Datasets to which you have access. Select the dataset that you want to mount in this project.
To access a Dataset, you must be an Owner, Contributor, Project Importer, or Results Consumer on the project that contains the Dataset.
Under Shared Datasets you can see the Dataset that you mounted. The Path for the Dataset points to a directory where you will find the mounted Dataset in your project’s executions. When mounted this way, the Dataset as well as any associated snapshots are read-only.
Go to the dataset that you want to unmount.
At the end of its row, click the three vertical dots and click Unmount.
