cannot invoke scripts

[zhizhongpu]

My attempt:

1. installed through windows terminal: python -m pip install sioyek
2. downloaded script "embedded_annotations.py" to sioyek-windows-release/scripts/
3. add to prefs_user_config:
   execute_command_h python C:\sioyek-release-windows\scripts\embedded_annotations.py highlight "%1" "%4" "%3"
new_command _embed_annotations python -m sioyek.embed_annotations "%{sioyek_path}" "%{local_database}" "%{shared_database}" "%{file_path}"
4. add to keys_user.config:
   execute_command_h;add_highlight h
5. open a file and select a text and press hh
6. close sioyek and open file in MS Edge, observing no highlights.
