On ArcGIS Online when viewing items in the content tab, there is an "Item type" filter, the Form item type falls under the Apps category. However, in the subcategories, there is no Form option, and it does not show in any of the subcategories that are available.
The most needed part of the solution, I suggest that a Form option is added to filter the Survey123 forms.
I also think it could be beneficial to have a Survey123 category that filters both the forms and the feature layers associated, and maybe the maps created by the publishing process as well. Or you could have these 3 items as sub-subcategories under Survey123.
I realized this idea would probably be better suited for the ArcGIS Online thread, but I found that the same idea had been posted Item Type Filter for Survey123 Form in AGO - Esri Community so I moved it back to Survey123 Ideas to hopefully gain more traction with frequent Survey123 users.
