You can use croc with tmux, install termux with F-Droid, then in termux install croc with:
pkg install croc
Grant termux access to your storage with: termux-setup-storage
(no root required but you will be prompted for storage access). Finally send files with croc. Links to tools used:

You can setup permanent passwords for convenient sending, just read through croc link.

@m_svo it looks like the app contains trackers from google for advertising and analytics.
