Lv-Micro python on Pi -Pico What next after building the Firmware.elf

Follwing the instructions for creating a lv_micropython port to Raspberry Pi Pico I have managed to build the firmware.elf file.

I’ll like some guidance on what to do next? and will this suffice for doing normal micropython projects on Thonny that don’t need LVGL? Stupid this may seem but I’ll appreciate any answer that helps.
