Enable native 'external-warm-transfers'?

[nastiazhyrnova]

Hi,
I am trying to enable external warm transfer in "custom transfer directory" feature, but it doesn't let me use it unless "Conference" feature or "native external warm transfer" is enabled:

flex-project-template/plugin-flex-ts-template-v2/src/feature-library/custom-transfer-directory/config.ts

Line 34 in f0ec43d

const nativeXwtEnabled = getFlexFeatureFlag('external-warm-transfers');

I have "Warm transfers" enabled under Features:

However, it seems to be appearing in store under flex-warm-transfers and not under external-warm-transfers. Where could I enable this native feature, or is it an error and it refers to flex-warm-transfers?

The native feature the alert is referring to cannot be enabled manually and is no longer supported, so you will need to enable the conference feature if you would like to use the external warm transfer option.
