Our company bytedance uses rustlang to write the common logic code of lark app for crossing platform. The result is that the performance and power-saving and development efficiency are much better than the native code of each platform.(Sorry, private data cannot be disclosed)
I would definitely recommend <strong>Lark</strong>, a new refresh collaboration tool integrating with chat, calendar, video and conference, mail, drive and space (doc, sheet, slide, etc.), and many third-party apps like Zendesk, Jira.
However, I also tested other tools and summarize the pros and cons of the top 10 collaboration tools. Refer to <strong>Best Collaboration Tools for 2019 (Top 10 Reviews)</strong> to learn more.
Definitely Lark(an all-in-one collaboration platform), with its own drive and wiki, you could create, share and edit files easily. Just have a try.
Also, I list 10 of the best collaboration tools here and you could refer to here to learn more information https://medium.com/@collaborationtool/best-collaboration-tools-for-2019-top-10-reviews-d7bee9044c12
bytedance is creating an office suite called lark suite: https://www.larksuite.com
Bytedance is partially owned (if not majority owned) by CCP.

This isn't anything new and was going to happen within next 5 years anyways. Better to take hit now vs later in my books.
If you are still looking for a solution a good free platform is www.larksuite.com (China team will need to download http://www.feishu.cn). We are receiving really good feedback on reliability of video over Zoom (which is currently banned) and Skype/Teams.
