I am planning a website upgrade to Joomla 4 and the website currently uses Jumi to embed a custom PHP script and external database search, into the Joomla website. Site visitors can carry out searches, browse the a-z directory and view the individual detail pages, that are all in an external database/script, but are all run and displayed within the Joomla page. Currently we use Jumi to embed the script into Joomla, but there isn't a Joomla 4 version and it doesn't look like an active project. Is this something that Sourcerer Pro can do?
