Improve access to event arguments

Hi,
I would like to ask for help. For ui.table I need to listen, on which row was clicked, and process the id of row in the rest of the code.
When I used ui.table (qtable), and table.on('rowClick', callback_function), the function has only one parameter, which doesn't contain the id of the row, or data of specific row etc. What do I wrong?

tbl1=ui.table(columns=columns_, rows=rows_, row_key='id', selection='single').props('')
print(tbl1.on('rowClick', lambda msg: print("> ",msg)))

and the output:

>  {'id': 4, 'type': 'rowClick', 'args': {'isTrusted': True, '_vts': 1680074011030}}
>  {'id': 4, 'type': 'rowClick', 'args': {'isTrusted': True, '_vts': 1680074011218}}
>  {'id': 4, 'type': 'rowClick', 'args': {'isTrusted': True, '_vts': 1680074011840}}
>  {'id': 4, 'type': 'rowClick', 'args': {'isTrusted': True, '_vts': 1680074012014}}

Thanks a lot, for your help.

We need to find a way to include more than the first event argument (see let handler = (e) => { in index.html). This also affects the argument-filtering mechanism (the args parameter).
