Looks good, thanks Jonah! I've added a couple of comments. Can you also double-check the GTM parameter value limit? I was under the impression that parameter names are limited to 40 but parameter values can be 100.

@MillenniumFalconMechanic my bad, I read the wrong limit, it is 100 characters. Some file names come very close to that, but I couldn't find any that have more than 100 characters, so this approach is probably fine

Breaking Changes @frano-m

• AzulFileDownloaded has the following new required props
  • entityName
    • string
    • The filename for the file being downloaded
  • relatedEntityId
    • string
    • The ID(s) of the dataset(s) or project(s) associated with the file
    • If there are multiple different associated datasets or projects, they should be stringified in the viewModelBuilder before being passed here
  • relatedEntityName
    • string
    • The name(s) of the dataset(s) or project(s) associated with the file
    • If there are multiple different associated datasets or projects, they should be stringified in the viewModelBuilder before being passed here
