IBM Watson TTS don't support swedish in HA

Many languages works fine with “Watson” TTS. As of 22th of october 2021 Watson support swedish with the voice:

sv-SE_IngridVoice

I can’t use it with HA. If I add it to the configuration.yaml:

  - platform: watson_tts
    watson_apikey: my_secret_key
    watson_url: https://api.eu-gb.text-to-speech.watson.cloud.ibm.com/instances/my_url
    voice: sv-SE_IngridVoice

and then I get a error message when I control the configuration:

Invalid config for [tts.watson_tts]: value must be one of ['ar-AR_OmarVoice', 'ar-MS_OmarVoice', 'de-DE_BirgitV2Voice', 'de-DE_BirgitV3Voice', 'de-DE_BirgitVoice', 'de-DE_DieterV2Voice', 'de-DE_DieterV3Voice', 'de-DE_DieterVoice', 'de-DE_ErikaV3Voice', 'en-AU_CraigVoice', 'en-AU_MadisonVoice', 'en-GB_CharlotteV3Voice', 'en-GB_JamesV3Voice', 'en-GB_KateV3Voice', 'en-GB_KateV3Voice', 'en-GB_KateVoice', 'en-GB_KateVoice', 'en-US_AllisonV2Voice', 'en-US_AllisonV3Voice', 'en-US_AllisonVoice', 'en-US_EmilyV3Voice', 'en-US_HenryV3Voice', 'en-US_KevinV3Voice', 'en-US_LisaV2Voice', 'en-US_LisaV3Voice', 'en-US_LisaVoice', 'en-US_MichaelV2Voice', 'en-US_MichaelV3Voice', 'en-US_MichaelVoice', 'en-US_OliviaV3Voice', 'es-ES_EnriqueV3Voice', 'es-ES_EnriqueVoice', 'es-ES_LauraV3Voice', 'es-ES_LauraVoice', 'es-LA_SofiaV3Voice', 'es-LA_SofiaVoice', 'es-US_SofiaV3Voice', 'es-US_SofiaVoice', 'fr-CA_LouiseV3Voice', 'fr-FR_NicolasV3Voice', 'fr-FR_ReneeV3Voice', 'fr-FR_ReneeVoice', 'it-IT_FrancescaV2Voice', 'it-IT_FrancescaV3Voice', 'it-IT_FrancescaVoice', 'ja-JP_EmiV3Voice', 'ja-JP_EmiVoice', 'ko-KR_HyunjunVoice', 'ko-KR_SiWooVoice', 'ko-KR_YoungmiVoice', 'ko-KR_YunaVoice', 'nl-NL_EmmaVoice', 'nl-NL_LiamVoice', 'pt-BR_IsabelaV3Voice', 'pt-BR_IsabelaVoice', 'zh-CN_LiNaVoice', 'zh-CN_WangWeiVoice', 'zh-CN_ZhangJingVoice'] for dictionary value @ data['voice']. Got 'sv-SE_IngridVoice'. (See ?, line ?).

I have Home Assistant 2021.11.4, supervisor-2021.10.8.
Can I do anything to make it work? Or will it solve it self in time?
Thanks!
