Clarification on StorageQuota and BonusStorageQuotaMb in SharePoint Online (CSOM / PowerShell)

I’ve been using CSOM and the Get-SPOTenant PowerShell cmdlet to retrieve storage-related data for my SharePoint Online tenant.

I noticed that the StorageQuota property accurately reflects the total storage available. However, I plan to purchase additional SharePoint Online storage and would like to clarify:

• Will the newly purchased additional storage be included in the value returned by the StorageQuota property?
• I also came across another property called BonusStorageQuotaMB which does not have any documention and seems like new one too— could someone please explain its purpose and how it differs from StorageQuota? 

Understanding how these properties behave is important for me to monitor and report tenant storage accurately.

Thanks in advance for your insights!
