Editors not having a button to get to a channels Ads Manager
People with the Editor role currently do not have a way to get to the Streamers Ads Manager page without simply knowing the link.
There is the Ads manager panel in the Stream Manager but that isn't the Ads Manager itself, more a fancy design for buttons already present in the Stream Manager page anyways.
There needs to be a button in the side bar of the Creator Dashboard allowing Editors to go to the Streamers actual Ads Manager at: https://dashboard.twitch.tv/u/USERNAME/monetization/ads
Editors having access to the Streamers Ads Manager is an advirtised feature of the Editor role. Example: Under the FAQ section "Can editors access Ads Manager? Yes." https://help.twitch.tv/s/article/ads-manager
Oddly, This ability isn't mentioned on Manage Roles page. Since this seems to be the only place where roles are partly explained, it should either be mentioned here, each role gets their own article, or all roles get a dedicated explanation article including everything a given role can do: https://help.twitch.tv/s/article/Managing-Roles-for-your-Channel
