Bitrix24 analogues for Joomla?

Question

CMS

Hello everyone! There is such a task - it is necessary to maintain corporate communication at a distance, and in general, we need a convenient service for communication, setting tasks, exchanging documentation, etc. Bitrix24 does not fit at all - it is not convenient for most employees, they require something else. What are convenient analogues?
And the most important question - our main company website is written in Joomla. Ideally - a corporate template, you can pay. I've been searching for over a month, but so far in vain.
Thank you!
