A way to update autocomplete database

[cicacica]

Is there a way to update the autocomplete database? Like after loading an adds on.

The autocomplete database is composed of Global and System names. Actually I do not know where a loaded add on would show up. Right now Global database gets updated at every autocomplete request, while the bigger System database is created only at the start of the Jupyter kernel and it does not get updated during a session.
