Limitations

Although you can publish up to five shortcuts (static and dynamic shortcuts combined) at a time for your app, most launchers can only display four.

However, there is no limit to the number of pinned shortcuts to your app that users can create. Even though your app cannot remove pinned shortcuts, it can still disable them.

Although other apps can't access the metadata within your shortcuts, the launcher itself can access this data. Therefore, these metadata should conceal sensitive user information.
