Opening JMP files stored in sharepoint library

[#1]

When I try to open JMP files stored in a sharepoint library, I get the following access problem.

Does anyone have a solution for this?

I think you might need to take an approach similar to this, used for excel files:

There might be a little more info in this thread too:

JMP v19 has an add-in that allows opening sharepoint files directly. JMP should delete this thread as it is misleading. Note, I haven't got the add-in working yet, but this is clearly a better solution.

The AddIn is just for Data Import from Sharepoint, not for working, saving, coworking with .jmp files,
right?

By synchronizing a Sharepoint Folder with OneDrive, one can do part of it - still with a lot of potential for future  improvement:
