Can't add a DMARC record to my domain

How can I add a DMARC if I have a conflict in my Wix Domain?

I purchased a Google workspace with 3 users externally to Wix and updated the SPF and DKIM. According to the Google Admin Toolbox, they are working properly, but every Email I send out from all three users, get to the recipient Spam folder, unless we had prior communication. I understand I also need to set up a DMARC record (although I understand this is for mass emails).
I generated a DMARC record but when I tried to add it, I can’t because Wix have added a DMARC record for the email aliases, and only one DMARC record can be added to a domain. See screenshot below.

I talked with Wix support but the guy was useless.
What can I do?? all I want is for the Emails to not go to Spam!

Hi Jordan,

Save your current record on notepad just in case you need
to revert back to it.

Try this new record as it worked for me:
_dmarc.easylandon.co.uk

Please let me know if this helps you.
