First, thank you for answering Ashley, 6 years ago that I have been following you from Construct Classic and it is very important to me and for the community that you can stay active, in your times, through the forum.
With support I mean that they give us the "plugin" tool to do the rest for us.
I suppose I should have documentation on how to apply it to these servers and the rest would be to link it to Onesignal or Firebase already on our own. The support would be to be updated the plugin before any change of Onesignal or Firebase and still be compatible with C3.
On the other hand, if all the above mentioned is not possible.
Provide facilities to users to implement these tools with documentation for those who want to venture (with some intermediate knowledge) to make a plugin on their own.
For example there is the option of Enhance. But I still have no idea how it works and link it to C3 push notifications, the One signal server. This may be the responsibility of Enhance but it would be good to be able to offer this service having already done half.
Thanks for your time.
Ashley
