If you installed SEED’s version 1.0 of the XIAO BLE Sense then you should be seeing this “example” file-tree. This comes with all the required libraries. If you do not have this file-tree showing under examples, then uninstall and reinstall version 1.0 (Adafruit) of the SEEED XIAO BLE Sense and check again.
Version 2.6.1 (Mbed) of the XIAO BLE Sense surely has a different structure and library.
