NVRnoob

is there anyone that can help me with this? I want to send the motion activated video recordings from my reolink NVR to a cloud service like Dropbox or One Drive but I don't know how. I have 2gb on dropbox and 5gb on One drive with the option to upgrade my One drive storage for only $2 but I feel 5gb should be enough since It will only record when it senses motion. Can anyone walk me through how to do this? Keep in mind that I am completely new to NVRs and security cameras. Any help would be greatly appreciated
