How to use the relevant parameters for refresh token authentication method in the `openid-connect` plugin

We are trying to use the refresh token authentication method with the openid-connect plugin but it is not clear how to make this work when setting refresh_token_param_type to body. What is an example of how to configure the openid-connect plugin, and send the refresh token in a body

The refresh_token_param_type parameter determines where Kong will look for the refresh token in an incoming request.

If this is set to body only then kong expects the refresh token to be sent as part of the request body. The body can be either in a JSON or form url encoded.

These are two curl examples:

curl --request POST \
--url <kong_proxy_endpoint> \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data refresh-token=<token>

curl --request POST \
--url <kong_proxy_endpoint> \
--header 'Content-Type: application/json' \
--data '{"refresh-token": "<token>"}'

Note that the refresh_token_param_name parameter determines what key Kong will be looking for the token for. For the above examples to work, refresh_token_param_name needs to be set to refresh-token
