How to open an Action of type URL in the current window?

Content (required):

Hello,

we have created an action (source URL) in Service Request. This URL is a deep link to the Messages subtab in the current Service Request. We need this URL to be opened in the current window but the Display mode is disabled and the default value is "New Window." How can this link be open in the current window?

Thank you!
