You'll need to put your flight controller into DFU (Device Firmware Update) mode. This will allow you to update the firmware. To do this, you'll need to hold the bootloader button on your flight controller (usually a tiny black button next to the USB Port.

3. Full Chip Erase :
Before updating the firmware, it's important to perform a full chip erase. This will erase any previous firmware from the flight controller and ensure that the new firmware is installed correctly. To do this, select the "Full Chip Erase" option before clicking on "Flash Firmware."
4. Minimize Firmware Size with Cloud Builds :
Betaflight offers "Cloud Builds" as an option to minimize the firmware size. This option allows you to build a custom firmware version with only the features you need, reducing the size of the firmware and freeing up memory on your flight controller. You can select this option in the Betaflight Configurator before clicking on "Flash Firmware."
