[SOLVED] Chrome Selenium CDP Bidi API - Next Commands sended to Target Session have no effect while the initial one does work

Hello everyone I'm facing a big trouble trying to hook TargetCreated Event and sending CDP commands to every new target found.

I'm using the last Selenium & Chrome.

I start a bidi session and send my commands and it work as expected.

async with self.driver.bidi_connection() as connection:
    self.cdp_bidi_main_session, self.cdp_bidi_main_devtools, self.cdp_cdp = connection.session, connection.devtools, connection.cdp
    await self.cdp_bidi_main_session.execute(self.cdp_bidi_main_devtools.page.enable())
    await self.__inject_javascript_object_via_bidi(self.cdp_bidi_main_session, self.cdp_bidi_main_devtools)

The javascript properties are successfully overrided.

But then, while listening for the TargetCreated Event and receiving them successfully, attaching to the target and then initiating a session to send commands don't work as expected...

event = new_targetcreated_event_received
async with self.driver.bidi_connection_with_target(event.target_info.target_id, self.target_attached_counter) as connection: -> I have modified selenium bidi source to make us able choosing session target and incrementing command ids
    cdp_bidi_main_session, cdp_bidi_main_devtools, cdp_cdp, cdp_ws_url = connection.session, connection.devtools, connection.cdp, connection.ws_url
    await cdp_bidi_main_session.execute(cdp_bidi_main_devtools.page.enable())
    # await trio.sleep(2) -> no differences
    await self.__inject_javascript_object_via_bidi(cdp_bidi_main_session, cdp_bidi_main_devtools)

I have struggled to try many different things :

Using a manual session command sender e.g: https://github.com/scivisum/browser-debugger-tools/
Understanding deeply WS CDPs protocol but nothing to do...

What I didn't tried :

Detach from a session before initiating a new one because very hard to do as it will kill the listener...

Here is a sample output of the command sended, as you notice this should work as expected...

P.S : I have modified the source code of selenium bidi so we can specify target session and command ids in session opening.
