Unable to Use Paste Option in Slicer Visual

Hi VannurVali ,
Thanks for reaching out to Microsoft Fabric Community.

For the Paste option to work in Power BI Desktop when copying values from sources such as Excel or Notepad, a permission prompt may appear when you copied some values and open Power BI Desktop.

A pop up similar to the one shown below will appear, asking for permission to access the clipboard. You need to click Allow for the Paste functionality to work.

If this prompt was missed earlier, the permission can still be enabled manually through Microsoft Edge site settings. You can open the site permission page directly using the following URL:

edge://settings/privacy/sitePermissions/allSites/siteDetails?site=https%3A%2F%2Fms-pbi.pbi.microsoft.com

On this page, locate the Clipboard permission and change it to Allow, as shown below.

After updating this setting, the Paste option in Power BI Desktop should become available. It may take a few moments for the change to take effect.

Hope this helps. Please reach out for further assistance.
Thank you.
