PARSE and Serial print NMEA Argument

I am new in Arduino ,

I want to take NMEA sentence from the GPS and parse them with the code below.
How can I print the parsed sentence argument in serial monitor? what I am doing wrong.
Please help.

#include <AltSoftSerial.h>
#include <Wire.h>
#include <NMEA0183.h>
#include <NMEAParser.h>
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x27, 16, 2);

// matches Zihatec RS422/RS485 shield
AltSoftSerial gps;
NMEA0183 nmea;
NMEAParser<4> parser;
float gprmc;
float gprmb;
  
void handleGPRMC(void)
{
  float test;
  if (parser.getArg(4, test))
  {
    gprmc = test;
    Serial.print(gprmc);
  }
}

void handleGPRMB(void)
{
  float test1;
  if (parser.getArg(4, test1))
  {
    gprmb = test1;
    
     Serial.print(gprmb);
  }
}


void setup() {
  Serial.begin(4800);
  gps.begin(4800);
  Serial.println("AltSoftSerial Test Begin");
  // Start Serial
  while (!Serial);
  Serial.println("NMEA0183 parser test");
   // Start LCD
   lcd.begin();
   lcd.backlight();
   parser.addHandler("GPRMB", handleGPRMB);
   parser.addHandler("GPRMC", handleGPRMC);


}

void loop()
// Reveive data from GPS
{ 
  lcd.setCursor(0,0);
  
  if (gps.available())
  {
    char c = gps.read();
    if (nmea.update(c))

    {
      Serial.print("NMEA0183 sentence accepted (");
      Serial.print(nmea.getFields());
      Serial.print(" fields): ");
      Serial.write(nmea.getSentence());
      Serial.println();
// Display Data from GPS  
        lcd.clear();//Clean the screen      
        lcd.setCursor(0,0);
        lcd.print(nmea.getFields());
        lcd.setCursor(3,0);
        lcd.print(" data received ");
        lcd.setCursor(0,1);
        lcd.print(nmea.getSentence());
//  if (Serial.available()) {
    parser << Serial.read();
   
   
    
//  }

      }
      }
      }

and the following input:

22:05:02.341 → NMEA0183 sentence accepted (12 fields): $GPRMC,190502,A,3645.4300,N,03432.8414,E,0.0,101.6,051020,4.1,E,A1D
