When I request curl --location --request POST 'connectapi.garmin.com/.../access_token \
--header 'Authorization: OAuth oauth_nonce="$oauthNonce", oauth_consumer_key="$consumerKey", oauth_timestamp="$oauthTimestamp", oauth_signature_method="HMAC-SHA1", oauth_version="1.0"'
then return status 400 Message Missing signature.
How to get OAuth signature??? Thanks
