Edge Extension not working - Could not communicate

Hey @Daniel_H-E

A. Before processing the In Private window, add processing to launch Edge (normal mode instead of In Private window) by the “Open Browser” or “Use Application/Browser” activity.
“ChromeNativeMessagingHost.exe” will automatically start when you open the Edge browser (normal mode, not the In Private window), so you can get the elements of the In Private window from Studio/Robot.
The disadvantage of this method is that it requires changes to the automation project.

B. Set the “Incognito/Private Window” option in the “Use Application/Browser” activity to False and use “CustomFolder” in “User Data Folder Mode” instead of this option.
Information such as cookies can be cleared by deleting the custom folder.
The disadvantage of this method is that it requires changes to the automation project.

C. Install UiPath MV2 extension.
It can be installed by adding the extension ID “hmpkmolbbcopahpbplbdaapacncbbc” to the ExtensionInstallForcelist group policy.
The advantage of this method is that no changes to the automation project are required.
The disadvantage of this method is that the user must manually enable the “Allow in InPrivate” option in UiPath’s browser extension.

D. Downgrade your Edge browser to version 114.
