Power BI custom connectors for manipulating data from API endpoints

We are creating a custom connectors for manipulating data from API endpoints by passing necessary parameters to an endpoint. As one of our requirement is to pass array of strings/list of strings as a required parameter to the API. For e.g. 

Then after selecting the required parameter the endpoint would look like - 

curl --request GET \
--url 'https://api.example.com/fleet/vehicles/stats/history?types=auxInput6,auxInput13' \
--header 'accept: application/json'

Any lead would be appreciated..
