Hi I'm having issues decoding a message transmitted by a ESP32 transmitting from a RMF95W LoRa Transceiver.

I'm transmitting with the following settings: SF: 7, BW: 125k, C/R: 4/8, Frequency: 915MHz (Bellow is the screenshot of the Arduino IDE configuring the transmit settings. I am transmitting a simple string of "AABBCC"

On the GNU radio side I have the following setup (I am using an RTL-SDR). Based on the tutorial I implemented an offset:
