As far as I know you can't, but what I did was to connect the drive to a PC (Windows or Linux) and make a SMB share of it. There is an app on F-Droid that can connect to SMB shares.
Take out the hard drive out of your laptop and put the drive for the server in it, install Debian using the built in monitor and keyboard of your laptop.
And recently Llama3 and Mixtral!
I've a Dreame L10s Ultra flashed with it, very happy with my purchase. A bit scary to install everything but if you read the instructions before doing it you should be fine :)
I use SplittyPie allot with my friends if we go on a trip/do something together. Works really well. You can install it as a PWA and it's FOSS ;)
RSS Guard seems to have support for Google Reader API, so FreshRSS is also supported. It's also a Qt application. You can also find other clients on the 3rd party clients page of FreshRSS
There are a lot of different methodes you could try. I think the easiest is to connect both systems with a (mesh)VPN like Wireguard, ZeroTier or Tailscale. Then you can simply copy stuff over using rsync -a (archive mode) with a cronjob or using special tools like Borg backup, kopia, etc
I don't think there is an app for something like that, but maybe you can try using Penpot in a browser?
I had the same issue with my Anonaddy alias, I just made an alias using my domain name and works fine now. It's unfortunate that so many project are on shithub.
