How to have access to an online MS Form responses with code?

As there is no available feature in MS Graph API to have access to MS Form responses (LINK), what's the code solution to have access to shared online MS Form responses?

I know the following available approaches:

• Manually download the responses by clicking on Responses -> Open in Excel and then upload it to the target location (It's a completely manual process and could not be automated by a code script which is not desired at all in my case)
• Share with a group first which gives me the option to have online access to the response file by clicking on Responses -> Open in Excel. This time it automatically creates an excel file in the group's OneDrive instead of downloading the file. Now I could read the excel file via MS Graph API. (This solution works but I need to share the Form with a group first and then manually click Responses -> Open in Excel to create the excel file)

Any thought that assists to have a complete code solution is appreciated

I would stick with the above approaches which you said above. In addition, you can consider using Microsoft Flow or Power automate to perform the above to automate the above approach. AFAIK i failed to see any Graph API exposed on this so far. Being said that i would suggest you can consider filing Microsoft Uservoice - so that they can consider implementing it. You upvoted the the uservoice as well.
