How to use in the "assets" app

There are different ways to use the module.

Option 1: Overwrite the magnolia dam app decoration file in the resources app.

Find the file in the decorations app and edit it.

Add the item usage workbench code snippet to the workbench column. You can add additional column properties like label and width. See https://docs.magnolia-cms.com/product-docs/6.2/Apps/App-configuration/Column-definition.html#_column_properties for all list of all properties.

itemUsage: &itemUsage
  $type: itemIdUsageColumn
  descriptionGenerator: ch.esense.itemusage.ItemUsageDescriptionGenerator

After closing and re-open the dam app, the new column appears in tree workbench.

Add the following folder structure to your modules decorations folder.

dam/apps

Create a yaml file

dam.subApps.jcrBrowser.workbench.yaml
