The website instructions for installing the Pi version of Gsender say to download the Appimage copy (strangely, they also offer a .deb version but there are no instructions on how to install it).
Anyway, there is no place I can see to choose which version I want to download, and the download link on the website front page forces you to download the .deb version (for which there are no installation instructions).
Where can I go to download the Appimage version of Gsender
OR
How do I install the .deb image on my Pi 5?
