HM-10 not sending from Arduino Uno to BT app

Hi! I'm trying to get an HM-10 to send and receive information between an app and an Arduino Uno. I'm using the Bluetooth Serial Monitor app on an Android phone, and here is my code:

#include <SoftwareSerial.h>

SoftwareSerial HM10(2,3);

void setup() {
  
  Serial.begin(9600);
  HM10.begin(9600);

}

void loop() {
  
  if (HM10.available()) {
   Serial.write(HM10.read());
    }

  if (Serial.available()) {
    HM10.write(Serial.read());
  }
}

I have the HM-10 TXD connected to pin 2 on the Arduino Uno and the RXD connected to pin 3. I am able to send strings from the app to the arduino, but not the other way around.
