Hello @lakshmi_laksh ,
A UI action can be used to add a related link to the Project form that opens in a new window in a popup way when clicked. For example, I successfully implemented a similar requirement on the Incident form by creating a UI action that opens the current caller's information in a new window when a related link is clicked.
Here is the related link added as a reference image,
When you click on the Open Caller Related link, it will open the current incident caller information in a new window as a popup. Change the script according to your requirement.
If my answer helped you in any way, please then mark it as helpful 👍.
