Possibly undocumented esp_hid APIs?

[ImproperCatGirl]

In the Bluetooth HID Host Demo (https://github.com/espressif/esp-idf/tr ... p_hid_host), A set of APIs named esp_hid is used.
However, I can't find any documentation in the programming guide for that. The most I can get is some docs for BT classic HID host, which is something implemented using the generic esp_hid APIs, not the esp_hid APIs themselves.

There is an open GitHub issue (https://github.com/espressif/esp-idf/issues/5767) for this, but nothing seems to be solved after the issue has been opened.

Question: Is there any documentation for this set of APIs? If not, when will it be released?
