The Odils Learning Foundation is a UK-based charity For Refugees, Asylum Seekers and Migrant Groups. They have created a number of useful and practical videos focused on learning Email (as well as a specific focus on Gmail), Zoom, and Microsoft Teams. This complements written resources they have created, such as Getting Started With Zoom.
Videos are available in Arabic, Bengali, Bulgarian, Dari, English, Farsi, Russian, Sorani, Tigrinya. Their playlists also include multilingual COVID-19 advice.
I've embedded the digital help playlists below.
