I tried the Azure Function Deployment with Github actions and it was successful.
Initially, When I deployed the Function it was not visible, Refer below:-

Make sure your init.py and function.json is inside one directory and other files are outside that directory for the deployment to work successfully, Refer below:-
Reference:- SO Thread answer by jsprovoke

Now, I deployed the Function with Github action and the Function was visible in the Portal refer below:-
Refer my complete github workflow in this Link.
