I'm trying to get facebook ads for messenger(ads to messenger).
I couldn't find the metrics or related dimensions in side bar.
as you are more familiar with the missing item, please visit our support documentation for missing metrics / dimensions to find instructions on how to see if it has come available.
If you manage to find the missing metric or dimension, please post a link to that site in to this ticket. We'll let our development team know of it and they will contact you once it's added to Supermetrics. Please note that fitting the missing metric/dimension to data source connector may take some time. We appreciate your help with this.
