drf-spectacular doesn't figure out filters correctly if i create custom filter backend

[angryfoxx]

I created custom filter backend class to use in my license page that page cover multiple action in it.
Whatever i couldn't see filter options correctly in openapi because below code doesn't respect action.

drf-spectacular/drf_spectacular/openapi.py

Line 148 in 02971bd

return self.view.action == 'list'
