Hi Liam,
esp32 not use SoftwareSerial, but redefine the pin for the hardware serial, check the constructor on this article
Ebyte LoRa E32 device for Arduino, esp32 or esp8266: WOR (wake on radio) and new ESP32 shield – 8
LoRa_E32 e32ttl(&Serial2, 15, 21, 19); // RX AUX M0 M1
//LoRa_E32 e32ttl(&Serial2, 22, 4, 18, 21, 19, UART_BPS_RATE_9600); // esp32 RX <-- e22 TX, esp32 TX --> e22 RX AUX M0 M1
// -------------------------------------
You can get more information to configure the parameter here

If you have other difficult write here.
Bye Renzo
