How does cross company collabration works?

If Company A is having SolidWorks 3DEXPERIENCE and Company B as 3DEXPERIENCE SolidWorks Standard

Now the Company A is the main Branch and the Company B need to acces the file from Company A from the platform as the roles are given without license to acces the file from Comapany A

Is it possible to Acces the files from them as the version is not the same where the Company A as the Destop SolidWorks Connector and the Company B as the 3DEXPERIENCE SolidWorks Connected?...
