Function custom domain does not contain a certificate

So I am having this issue that any time I create a function it will generate a custom domain for the function but the domain is using a self signed certificate instead of let's encrypt cert.

Someone has once faced this issue but it was later forgotten without a fix or a solution to this problem, pls I am experiencing it now and it is quite painful to use.

Thanks in advance.

Ya...well probably add some documentation on how to set this up later....I think you might be able to configure traefik to do something for this
