could not patch client to support firebase addon with grant type id_token

We tried to patch our newly created client to work with the firebase addon
like this (suggested by Error "Grant type '' not allowed for the client" after saving settings - Auth0 Community )
– and it DIDN’T WORK (ADMIN is an “all-allowed” auth0-admin-api token )

curl -X PATCH \
 -H 'Content-Type: application/json' \
 -H "Authorization: Bearer $ADMIN" \
 https://******* -d\
 '{ "grant_types": "authorization_code","implicit","refresh_token", ""] }'

--> {"statusCode":400,"error":"Bad Request","message":"Invalid grant types:"}

Is there any chance to add the missing legacy grant_types?

This situation was handled through a different support channel so I’ll be closing this question. As a summary, legacy grant types are not available by default for tenants created after the cut-off date, however, in some scenarios where a customer has multiple tenants and some were already using the functionality it may be possible to enable the legacy grant types even on a new tenant. However, this is analyzed on a case by case basis and only as a last resort measure.
