collaborate functionality in RH with sharepoint

Hello everybody!

I'm here again because I need your suggestions! I try to create a connection on sharepoint on line to collaborate with other collegues on the same RH project.

I have a RH 2022.3.93 and I follow these step (which I find on RH user manual)

• configured a new connection profile
• then I wanted to add a new RH project in a folder of a documentation library of my sharepoint online, so I open the RH project, I want to add in sharepoint, and click on Collaborate > Add project and select my SharePoint Online connection profile
• but when I click on my Online connection profile I can't see the folder created in the SP site, so the check in dialog box doesn't open and the following window appears
   

Could you please help me to understand what I do wrong?

Thanks in advance!
