Subject: Request to Use Google Slides
Hi Miss K,
Thank you for providing the PowerPoint presentation. Unfortunately, I am unable to use PowerPoint due to personal reasons. Would it be alright if I converted the presentation into Google Slides for my use?
I appreciate your understanding.
Best regards,
Olivia
