How to Create an End-User Editable Text Box in BI Viewer Accessible From OnePlace?

I’m trying to create a text box component that can be added to a BI Viewer and easily updated by end users directly in OnePlace. The goal is for the users to be able to edit the text without having to modify anything in the underlying application or configuration.

Here’s what I’ve attempted so far:

• Created a string parameter intended to store the text.
• Tried adding a dashboard parameter control (such as a text box) linked to that parameter.
• Embedded it into the BI Viewer view.

However, this approach didn’t yield the desired result. The text either doesn’t update as expected, or isn’t visible to the user in the way I intended.

Has anyone successfully implemented a user-editable text box that can be directly manipulated by end users in OnePlace and reflected in a BI Viewer component? Any guidance, best practices, or examples would be greatly appreciated!

Thanks in advance for your help.
