There are a bunch of great forks / integrations of WinApps project (& similar) on GitHub now - I highly recommend LinOffice (https://github.com/eylenburg/linoffice/) for those who need native Office 365 (I needed to reluctantly edit Excel macros, and dual booting from Linux into Windows many times a day wasn't efficient).
It's great to support the team at CrossOver, but if you need a recent version of office or a Windows application that Wine/Proton doesn't support properly, then Docker/Podman running QEMU/KVM in the background is surprisingly performant (which Lin Office orchestrates all for you).
