I have an extension version conflict problem on my Joomla site, for which the recommended solution is to change the civicrm dependencies via composer (Guzzle conflict between CiviCRM and Community Builder (Joomla)?).
However, this CiviCRM was installed via the Joomla plugin system, and has never been managed by composer. So essentially, I don't know how to implement the solution :-)
Composer is installed on the server where CiviCRM resides. Is it possible to set up composer to manage the Civicrm instance after-the-fact, so I can change these dependencies? I can't find any documentation on how to do this (all the documentation I'm finding re: CiviCRM and composer are for Drupal).
Help appreciated, thanks.
