Team-Managed Custom Filters Access via API

Hi,
For company-managed projects there is an endpoint to get all the custom filters like so

curl --request GET \
  --url 'https://your-domain.atlassian.net/rest/agile/1.0/board/{boardId}/quickfilter' \
  --header 'Authorization: Bearer <access_token>' \
  --header 'Accept: application/json'

However, there isn’t a similar endpoint for team-managed projects because they don’t use the agile/1.0/ API.
Is there a way to identify the selected Custom Filters for a particular team-managed project? The endpoint est/api/3/filter/search? doesn’t return results as expected.
Thanks,
Jerry
