How can I add custom requirement to buildozer.spec file

My buildozer.spec file looks like this.

requirements = python3, mysql-connector-python, plyer, android, futures, datetime,kivy, kivymd

I want to use development version of kivymd so I changed that to something like this:

requirements = python3, mysql-connector-python, plyer, android, futures, datetime, https://github.com/kivymd/KivyMD/archive/master.zip

But it doesn't seams to work. It crashes immediately.
I tried also this one:

requirements = python3, mysql-connector-python, plyer, android, futures, datetime, kivy, https://github.com/kivymd/KivyMD/archive/master.zip

but I've got the same result.

What is the correct way to change the requirements?
Or maybe I can download and add it somehow locally?

EDIT:
I've realise that i can use option requirements.source so i did this:

requirements = python3, mysql-connector-python, plyer, android, futures, datetime, kivy, kivymd# (str) Custom source folders for requirements# Sets custom source for any requirements with recipesrequirements.source.kivymd = /home/sylwek/buildozer_Test1/KivyMD-master

But it still doesn't work...
