@rivanfebrian123 Thank you so much for your time on this! It's very appreciated.

Could you please rebase from develop? Some changes has been merged yesterday and they are not into your branch yet apparently.

Apart from that, it looks good. Thanks again!

Ah... good to know

Could you please rebase from develop?

Actually, it wasn't possible to rebase as there was a merge conflict. So I revert commits in the branch and force-push instead. But don't worry, we're good to go now
