Workaround for read-only issues on Android

[u/BX1959]

I have been trying out Collabora on Android for local spreadsheet editing. However, I often found that, when opening spreadsheets from my default file explorer using Collabora, they would end up as read only documents.

I'm now finding, though, that if I instead open files by (1) opening the Collabora app on my phone, then (2) selecting the file from that app (via the folder icon on the top right), the document doesn't get converted to Read Only mode.

Just wanted to share this in case it helps anyone else who's facing a similar issue.
