Call directly with contact name

I am making a app for that i need to “Phone_Call” component to call directly with name no need to add number for e.g :

Contacts:

Username in contact : Jack
Jack’s phone number : 1220239292

So when i use the “Phone_call” component i just want to use contact name “Jack” to call directly instead of phone number (and yeah without contact picker).

is it possible ?

Try one of the following extensions
