It is possible to use a a raspberry Pi Pico as HID The code below can be run and it types in to the source code. You would need to add a switch and save the code in code.py to auto run it.

AutoType Keyboard for the Raspberry PICO
Overview:-
I needed to automate typing a conversation, between two people over an App like a Chat Bot session.
The App needed a slow stream of repeatable text to soak test it and fill up scroll buffers, over many minutes.
It needed a trickle of characters as if typed on the App's keyboard(s).
I can plug in an external keyboard at each end.
The Arduino IDE has Keyboard examples.
Raspberry PICO were available from Farnell for about 6 GBP.
There are examples using them as USB Keyboards.
It is impractical to read the display, but a wire can be used between two of these devices, so they can type in turn.
Typically, Person A: types to Person B: and B: types back.

It is easy to get the Arduino IDE to work.

I needed to automate typing a conversation, between two people over an App like a Chat Bot session.
The App needed a slow stream of repeatable text to soak test it and fill up scroll buffers, over many minutes.
It needed a trickle of characters as if typed on the App's keyboard(s).
I can plug an external keyboard at each end, which could be two of these PICOs. This is not essential.
It is impracticle to read the display, but a wire can be used between two of these devices, so they can type in turn.
Typically, Person A: types to Person B: and B: types back.
* timeline:-
* A: | typing |GA| waiting | typing |GA| waiting | typing
* B: | waiting | typing |GA| waiting | typing |GA| waiting
*
* A: types pressing keys on a keyboard, at up to 10 characters a second or slower
* A: hands over to B: by sending "GA" to Go Ahead, then waits
* B: reads the typing and can type but should wait until A: stops typing, before starting.
* B: types and A: waits til B: stops.
*
* Typing on a smart phone soft keyboard is slower.
*
* some devices display both conversations in a single line of text, making it difficult to read.
*
Use a one PIN Wired Or BUS wire to communicate between two of these PICOs.
* Assert Low when Typing,
* Stop typing when "\n" found - Users send GA for Go Ahead
* Wait for it to go high, before sarting to type.
pull up

-----+-----+-----+----------+--- Wired OR buss - Assert low when typing.

[ A ] [ B ] [ SW ]
[ A ] and [ B ] Wait for high to start typing and assert a low
[SW] is a switch which can pull low to inhibit typing.
on start up hold off typing.
When waiting look for ----____ before starting typing.
