Pass additional filters with search text from Search UI to App search

Thanks for the update ….
Through below code, I am able to update config

searchQuery: {
filters: [
{
field: "world_heritage_site",
values: ["true"]
}
]

Is there any explicit way to call refresh result/perform search with new config?

I just want to trigger the function from my button in filter panel that is being trigger on search button associated with SearchBox component of search ui.

How do I use addfilter function? I went through documentation but unable to find the way to addfilter..in which object I will get this method?
