You are configuring CyberArk to use HTML5 gateways exclusively for PSM connections.

To configure CyberArk to use HTML5 gateways exclusively for PSM connections, you need to set the DefaultConnectionMethod to HTML5 in the PVWA. This is done by logging in to the PVWA with an administrative user, navigating to Options > Privileged Session Management UI, and setting the DefaultConnectionMethod to HTML51. This configuration ensures that HTML5 sessions are triggered only for PSM machines associated with the HTML5 Gateway1.
