Pull Request Overview

This pull request addresses the issue of avatar initials not showing in the shares table by switching the bound property from userName to displayName.

• Updated bindings to use avatar.displayName instead of avatar.userName in two locations.

Comments suppressed due to low confidence (2)

packages/web-pkg/src/components/FilesList/ResourceTable.vue:211

• Ensure that all avatar objects reliably include the displayName property or provide an appropriate fallback if not, to avoid potential display issues.

              :user-name="avatar.displayName"

packages/web-pkg/src/components/FilesList/ResourceTable.vue:238

• Ensure that the update to use displayName is consistently supported by the data model across all usages, considering the possibility of missing values.

              :user-name="avatar.displayName"
