I am a Linux Student User, they gove me a presentation to do, and I simply used the PowerPoint Online Tool.
Of course, it might lack some features, but for an assignment every once and a while, was perfectly fine.
For the rest I always use Libre Office to complete my assignments, and convert the file to PDF afterward.
Maybe could this be achieved using a third party app? I would be interested, if it’s possible; my laptop battery is messed up, because it has always been at 100%.
