Microsoft Graph service exception Error code: accessDenied with Site.Selected Permission

Question

I have application which uploads files from S3 to a specific Sharepoint site using Microsoft graph Java SDK. I registered app called 'S3ToSharePoint' in Azure active directory, add Application type 'Sites.Selected' permission to my app since admin won't grant Sites.ReadWrite.All(Application) for security concern. In the description of 'Sites.Selected', it says 'Allow the application to access a subset of site collections without a signed in user. The specific site collections and the permissions granted will be configured in SharePoint Online. ' So I added this the account as owner(full access) in Sharepoint sites(not sure if this is the correct way to do configuration). But still got 'accessDenied' error when trying to upload to this Sharepoint sites. Does anyone know if this is the correct way? I saw someone use Sites.ReadWrite.All(Application) and that works for them. Not sure 'Sites.Selected' will do the same since it is in preview mode.

Hi @SUNOJ KUMAR YELURU ,
Thanks for the link, I checked all your links and I believe I choose the right set of permission. Basically, I am trying to use ClientCredentialProvider to get auth token since my app is a scheduled job which won't need user interaction. For scope, I use 'https://graph.microsoft.com/.default', which is standard for ClientCredentialProvider auth. The API permission the registered app has is https://graph.microsoft.com/Sites.Selected (Application Type), and it has been granted admin consent.
I have an updated debug screenshot for accessDenied info.

Hi @s-taxcomreporting SA ,
You could try to add Application Files.ReadWrite.All, Sites.ReadWrite.All permission.

I tested successfully with the following permissions.

Any resolution to this? Doesn't look like there's any documentation on the Sites.Selected permission level.
