I'll play tiebreaker here...

If you're using an integration which it looks like you are you should follow @leandrojmp suggestion.
Put in your settings in the@custom
template is the correct thing to do as it allow for upgrades in the integration package without overriding your settings -
If you're not using an integration and you want to create your own data stream then you should follow what @Rafa_Silva is suggesting. By the way I would argue you would just clone the base logs template and follow the same pattern. I gave an example of this here
It seems for your current case I would go with option 1.
