OneDrive Linux not synching shared folders

I installed OneDrive as described on this page: https://github.com/skilion/onedrive

Synchronization of files works like a charm.
Be aware that default (no parameters) synchronize and exit

However I am unable to get shared files in my~/OneDrive folder.

I do not see this option: go to the Shared files list, right click on the folder you want to sync and then click on "Add to my OneDrive"
Is it supposed on the one-drive-website?

(The files are shared by another person with me. On Windows there is another folder in the home directory next to the OneDrive root folder) .. is it supposed to be like this?

Note: it is an Office365 account.

What's your OneDrive account, personal Microsoft account or Office 365 work/school account?

The Add to my OneDrive option isn't available when:

• You're signed in with a work or school account.
• You've already added the folder to your OneDrive, or you have more than one folder selected. (You can't add multiple folders at the same time.)
• The item you're trying to add isn't a folder. Add to my OneDrive isn't available for individual files or for collections of files such as albums.
