Installing to desktop PCs from Edge and Chrome seems to work but the option to Add to home screen is not displayed on mobile devices (device used - Oneplus 6T).
Should investigate with debugging tools for physical devices and/or emulating an android device and checking logs for errors. Likely something to do with the service worker.
Update - I believe I was trying to download it wrong previously, as I can now open it in the Google App and then select "Add to home screen", and it get's downloaded to my device as an app.
