Thanks for this! Can you check if it works with #46 too?

Tested on a successful build (https://github.com/moonlitworks/without-romance/actions/runs/3210733592/jobs/5248407873) rebased on #46

Though, a few notes:

• I find that totp doesn't work when used twice, so i had test login only happen when it is using mfa files
• I removed the post-entrypoint from #46 as (a) the unescaped double quotes lead to docker: invalid reference format and (b) even with the double quotes escaped, it doesn't seem to locate $(pwd)/manifest.vdf correctly. Instead, I had to set output inside the main entrypoint

• Rebased this pr on #46 to test if this works with that, as per @davidmfinol's request
• Moved test login inside the else block to only run it when it is using mfa files
• Attempted to fix docker error by escaping double quotes in post-entrypoint
• Removed post-entrypoint entirely and set action output from the main entrypoint
