Assistance Needed Adding DMARC Record for Domain (Manual DNS Update)

Hi there,
I’m trying to complete Google Workspace authentication for my domain concordsoapcompany.com, and I need help adding a DMARC TXT record. I understand that DMARC records contain an underscore in the host name, which can’t be added from the customer control panel.

I’ve reached out through the normal support channels but haven’t received a reply yet, so I’m posting here in hopes that a Homestead representative can assist with the manual DNS update.

Could someone please help add the DMARC record to my domain’s DNS on the backend? This is the final step I need for my Google email setup to be fully authenticated.

Thank you—I appreciate the help.
Melissa
