Upload Google Slides vs PPT

What are you trying to do? (Detailed description)
Our company has moved away from Microsoft Office and everyone uses Google. There are a lot of issues when going through the whole downloading, converting and uploading process that could be avoided if there was a way to upload a Google Slide deck.

What is the challenge you’re experiencing?
See above

Do you have a workaround that you use right now?
Accept that it is more work for me.
