Siri shortcut not working

Hello,

I remember that once was possible to set a specific command for specific shortcut in some settings so that siri would intiate the shortcut but I cannot find it. If I name my shortcut for example - My love whatsup and say it to siri it does not do anything whilist a shortcut that I downloaded from someone a shortcut named action picker, it works… How do I specify a certaion phrase and link it with specific shortcut so that it worsk? I don`nt think you have only option to do it by saying siri the name of the shortcut. Or they changed it and now it is the only way?

Thank you
