Troubleshooting Make Integration Issues for Companion Site Partner Announcements

Hi! We have a variety of partners that offer discounts to our community and want to announce new partners to our Companion Site. We have a Make integration that pushes a message to the Slack channel when we add a new partner to our Airtable base. However, it won't publish to the Companion Site even when I try to manually publish the post. Is there a solution to this or is it just not recognizing Make integrations at the moment? Thanks in advance!
