Domain Verification: tilda landing and subdomains

We have the following case:

Our landing (let’s call it domain.com) is built with Tilda, and there is no option to upload an HTML file.

Our main platform is hosted at app.domain.com (CloudFront, S3, APIGateway, Lambda). We can make an endpoint that will return your file on this subdomain, though it will require a new release and make take a while.

All policies are hosted on landing (e.g. https://domain.com/privacy), and webhooks are sent to subdomain app.domain.com.

How should we proceed with verification in this case? We can use standard DNS validation as most other integrations do, if you provide such an option.

TIA

Update: I tried to just press “validate” and the verification suddenly passed. I have confirmed though that validation requirements are not fulfilled as of now - there is no such file at the requested location.
