How to use django filter_fields with ArrayField in DRF

Well I figured it out, lol. Needed to create a custom filter with lookup_exp='icontains'.

class CategoryFilter(filters.FilterSet):
    category = filters.CharFilter(lookup_expr='icontains')

    class Meta:
        model = Items
        fields = ('item', 'category')

class CategoryViewSet(viewsets.ModelViewSet):
    queryset = Items.objects.all()
    serializer_class = CategorySerializer
    filterset_class = CategoryFilter
