Is there a way to test multiplayer scenarios before publishing?

Trying to make a multiplayer scenario that has cinematics.
I have seen that cinematics create a lot of syncing problems etc.
Since i dont want to publish a non functioning mod, is there a way to test the multiplayer compatibility before publishing?

Is it as simple as manually putting the custom scenarios in both players their game files and then host a lobby? or will that create additional problems that would not appear with published mods?

Players can download scenarios through multiplayer, it gives them a warning that the host is using user generated content that has not been reviewed unless they’ve disabled the warning in the options.

Then it asks if they want to download the scenario.

The biggest issue will probably just be filling your lobby, you could try to find some people on the discord who will help you test and either fill or partially fill the lobby.
