Starting with the release of Strategy ONE (March 2024), dossiers are also known as dashboards.
Once a Strategy project has been configured with a link to Strategy Library (link ), each time a user creates or executes a Dossier a blue bar is shown to launch the current dossier in Strategy Library as seen on the screenshot below.

In order to disable this functionality for all users, the following steps can be taken:
1. Open sys_defaults.xml from [Strategy_Web_deployment]/WEB-INF/xml
2. Change the value (v) of the following line from 0 to 1.
<pr des="whether to disable the shareLinkBar in VI" n="disableShareLinkBar" scp="system" v="1" dt="boolean"/>
