How to make ingress use my TLS Certificate in Microk8s - kubernetes

Question

I have the following Ingress configuration:
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: http-ingress
spec:
rules:
- host: example-adress.com
http:
paths:
- path: /apple
pathType: Prefix
backend:
service:
name: apple-service
port:
number: 80
- path: /banana
pathType: Prefix
backend:
service:
name: banana-service
port:
number: 80
tls:
- hosts:
- example-adress.com
secretName: testsecret-tls
And i also created the Secret:
apiVersion: v1
kind: Secret
metadata:
name: testsecret-tls
namespace: default
data:
tls.crt: path to .crt
tls.key: Zpath to .key
type: kubernetes.io/tls
But when i connect to one of my services and check the certificate it says that it uses a cert created by Kubernetes Ingress Controller Fake certificate.
When i run microk8s kubectl describe ingress i get the following output:
Name: http-ingress
Namespace: default
Address: 127.0.0.1
Default backend: default-http-backend:80 (<error: endpoints "default-http-backend" not found>)
TLS:
testsecret-tls terminates example-adress.com
Rules:
Host Path Backends
---- ---- --------
example-adress.com
/apple apple-service:80 (10.1.55.17:5678)
/banana banana-service:80 (10.1.55.10:5678)
Annotations: <none>
Events:
Type Reason Age From Message
---- ------ ---- ---- -------
Normal CREATE 28m nginx-ingress-controller Ingress default/http-ingress
Normal UPDATE 20m (x2 over 28m) nginx-ingress-controller Ingress default/http-ingress
What do i need to change to make my Ingress use my Cert instead of generating a new one everytime?

Posting this out of comment as it works.
Based on your tls secret yaml, you tried to add certificate and private key using paths, which is not supported currently (reference)
Fragment from reference:
When using this type of Secret, the tls.key and the tls.crt key must be provided in the data (or stringData) field of the Secret configuration, although the API server doesn't actually validate the values for each key.
Therefore there are two suggestions how to move forward:
Add base64 encrypted values for key and certificate to tls secret
Allow kubernetes do it for you with the following command:
kubectl create secret tls testsecret-tls --cert=tls.cert --key=tls.key
