In case you need to help someone with a computer and want remote access, rather than using a proprietary option (& dealing with time limits & nagging & other hassles), try https://rustdesk.com which is #libre software. Supports remote desktop to/from many platforms (including Android & iOS & Linux). You can also easily run your own server, so you (and whoever you're helping/is helping you) don't have to trust *anyone* else. Want to run your own server? I can advise. It's easy with Docker.
