How do you write to Cloudflare KV when developing locally with wrangler dev?

I remember that you could write directly to Cloudflare KV's namespace when running wrangler dev locally.

name = "project_name"
main = "src/index.js"
compatibility_date = "2022-10-06"
type = "webpack"

account_id = "account_id..."
workers_dev = true

kv_namespaces = [
    { binding = "namespace_name", id = "id..." }
]

[env.staging]
kv_namespaces = [
    { binding = "namespace_name", id = "id..." }
]

[env.production]
kv_namespaces = [
    { binding = "namespace_name", id = "id..." }
]

name = "project_name"
main = "src/index.js"
compatibility_date = "2022-10-06"
type = "webpack"

account_id = "account_id..."
workers_dev = true

kv_namespaces = [
    { binding = "namespace_name", id = "id..." }
]

[env.staging]
kv_namespaces = [
    { binding = "namespace_name", id = "id..." }
]

[env.production]
kv_namespaces = [
    { binding = "namespace_name", id = "id..." }
]

This is what my wrangler.toml looks like. I am currently running by calling wrangler dev. I have logged in with wrangler. It was a while ago since I did this, maybe an update have come or so. Right now it writes to local cache at .wrangler/kv

dev in Wrangler 3 runs locally. If you want to access your actual remote namespaces, add --remote to the end of wrangler dev

Thanks Kian, I had missed that flag. I also forgot to add a preview_id to my kv_namespace. Now it writes to the preview_id when developing locally. Thanks again!

did you add the same id for both preview and id? ideally that must have worked
