Hi @Anonymous ,
Could you please share a bit more about your issue?
Could you please show more details about the one-way authentication error?
Further, do your end users have enough permission to access your OneDrive folder or OneDrive Excel file?
If you want these end users to be able to access your shared app, you must also share your OneDrive folder or OneDrive Excel file (the shared app connects to) to these users.
More details about sharing app resource, please check the following article:

In addition, please also check if these end users have purchased corresponding Office 365 license, so that, they could access OneDrive functionality.
Note: If you added OneDrive connector as data source in your app, these end users need to create a connection to OneDrive using their personal account when they using this shared app.
Best regards,
