Since Ingress integration has been removed from Gitlab I can't generate/renew certificates

How do I configure my kubernetes (namespace, issuer, certificate, ingress) now that the integration with ingress has been removed?

Since this integration has been removed from Gitlab my certificates are not generated/renewed for my backend deployment. My production one is gonna come to an end very soon and my platform will then be down…
Has anyone managed to replace the configuration in order to make it work like it used to?

Thanks in advance!
