It's my (@er2off) ports overlay with some ports that can be used by any FreeBSD user. All of these ports are planned to be merged into upstream in future.

Just clone this repo, cd to needed port and make install it.

$ git clone https://github.com/er2off/freebsd-ports
$ cd net-im/armcord
$ sudo make install # or other tool to go to root, I prefer doas

If you prefer poudriere instead, it's also possible:

poudriere ports -c -m git+http -p er2ports -U github.com/er2off/freebsd-ports
poudriere bulk -j 140amd64 -O er2ports # -f pkglist.txt or simply package names

I don't always test my ports build in poudriere because sometimes I'm lazy to wait until everything will be built. So if you found any issues, tell me.
