I’m trying on ASP.Net in C# to open a new url in a new tab but I’m always blocked by pop-ups, when I allow pop-ups it’s working, is there a way to open a new tab even if the pop-ups are blocked?

Here is my code:

protected void myFunc() {
   // start code
   
   // When doing this it's blocked by pop-ups
   ScriptManager.RegisterStartupScript(this, this.GetType(), "OpenNewTab", String.Format("window.open('{0}', '_blank');", url), true);
 
}
