Changing Space To Touch

How can I change the space press code to touch on screen for android

void Update(){
    		if (inTrigger & Input.GetKey(KeyCode.Space)) { 
    			ui.skorartisi (); 
    			Time.timeScale += 0.2F; 
    		}
    		if (!inTrigger & Input.GetKey(KeyCode.Space)) { 
    			can++; 
    
    		}

Simply change you input checking to Input.GetMouseButton(0) Like this

 void Update(){
             if (inTrigger && Input.GetMouseButton(0)) { 
                 ui.skorartisi (); 
                 Time.timeScale += 0.2F; 
             }
             if (!inTrigger & Input.GetMouseButton(0)) { 
                 can++; 
     
             }
}
