How has this been tested?

1. Change snowplow config on local env to report to snowplow micro

diff --git a/src/common/snowplow/snowplow_options.ts b/src/common/snowplow/snowplow_options.ts
index c0b43b9c..30946a28 100644

 export const snowplowBaseOptions: Omit<SnowplowOptions, 'enabled'> = {
   appId: 'gitlab_ide_extension',

+  endpoint: 'http://localhost::9091',//, 'https://snowplow.trx.gitlab.net',

 };
(END

2. Add gitlab account with PAT that only has read_api scope
3. Try to get any suggestion (that will fail since scope is missing)
4. Check snowplow micro at http://localhost:9091/micro/good
5. Find "api_status_code": 403
