When I upload a file to Lumo from Proton Drive, Lumo makes a suggestion to change something in the file. A word file for instance. I do the changes and want Lumo to check it again. But a file that has been once uploaded to Lumo cannot be "updated" it can be uploaded and then it is locked in practice. I need to rename the file if I want lumo to see the new version. My proposal is that once I have updated a file on Proton Drive that I have a possibility to remove the old version from the Lumo Chat and start fresh with the new version of the file. Alternatively, just with one button "replace old version" that makes it easier to work with updated files. On another note, when the file names are not very short, selecting a file from proton drive for lumo is a bit of a guess work. The possibility to have a larger field for selection of proton drive, maybe even on a separate window including change date or file size would be helpful.
