I am working off of the esp_hid_device example, as that seems to be the most aligned with my final project goal of mimicing a bluetooth device, and the main method of sending data that this example uses is a function called `esp_hidd_dev_input_set`. I cannot find documentation on this function, and while most of it seems self explanatory, I am confused as to what the "map index" parameter does.

The example is this one:

and the function is line 157
