Helm Chart persistence issue

Is there a way to configure persistence setting when modifying official localstack's chart pooled from https://localstack.github.io/helm-charts?

I tried this:
```values.yaml
localstack:
image:
repository: "gresau/localstack-persist"

nameOverride: localstack
fullnameOverride: localstack
startServices: s3,sqs
debug: false

# Don't expose external service ports range
containerPorts:
edge: 4566

persistence:
enabled: true
mountPath: /persisted-data
size: 5Gi

envVars:
#### Default localstack params: ####
# https://docs.localstack.cloud/aws/capabilities/state-management/persistence/

# disabling extra ports, keeping only 4566 for sqs & s3:
EXTERNAL_SERVICE_PORTS_START: "4566"
EXTERNAL_SERVICE_PORTS_END: "4567"

PERSISTENCE: "0" # default localstack param, doesn't work with community edition
#SNAPSHOT_SAVE_STRATEGY: "manual"

#### specific for `gresau/localstack-persist` params: ####
# https://github.com/GREsau/localstack-persist
PERSIST_FREQUENCY: "5" # how frequently, in seconds, to persist change to disk (default 10)

# Disabling all persist services expect for selected:
PERSIST_DEFAULT: "0"
PERSIST_S3: "1"
PERSIST_SQS: "1"

```

But my configuration is always overridden:

```sh
$kubectl describe pod localstack-xxx

Environment:
DEBUG: 0
...
Mounts:
/etc/localstack/init/ready.d from localstack-init-scripts-config (rw)
/var/lib/localstack from data (rw)
/var/run/secrets/kubernetes.io/serviceaccount from kube-api-access-7c28h (ro)

```
As you can see mount is this:
```
/var/lib/localstack from data (rw)
```
Instead of how it should be:
```
/persisted-data from data (rw)
```

The only way I could make it work is by applying post-patch, which is not ideal.

Any suggestions on how to do it in the right way? Do you have your version of charts? Thanks!
