Programme to send Signal messages from text files

Hi I am looking for a way to automatically send Signal messages based on text files in a folder.

The programme would
1) scan a folder for text files,
2) use the name of the text file as the number of whom to send it to,
3) use the content of the text file as the massage
4) once the message is sent in Signal, the programme would delete the text file

I have found this on Github https://github.com/signalapp/libsignal

And I also found this on Guthub https://github.com/signalapp/libsignal-service-java

This needs to all run locally on my windows 11 laptop.
