denied access feed /[id]/ Import for a feed item

I'm dealing with an older d8 site that has a feed element of a custom type with a custom processor. When I go to admin / content / feed and click on an existing one and go to feed / id / import, I get access denied. If I add a new one, I do not get the same error but am I trying to understand what support defined for the "import" operation for a feed?
