A small repair. Id use something such as Red Devil One Time for that, it’s lightweight, premixed & cures very quickly. Once the filler has cured, rub it down. Once you have it flush, use a couple of coats of water based undercoat then rub down again with finishing paper (fine grade sanding sponge pad is great on contours such as doorframes). Dust off with a dust brush then apply top coat

I too use Nextcloud & Joplin on all my machines. I also have LocalSend on desktops & phone as another option for quickly firing something over. Because I’m a nerd I also keep a copy of LocalSend portable on my keyring flash drive “just in case I need it” (I’ll almost certainly never need it).
