I have defined a request URL which gets triggerred whenever I click a button in my Slack channel.(** From the docs - Any interactions with shortcuts, modals, or interactive components (such as buttons, select menus, and datepickers) will be sent to a URL you specify.**). However, I require basic auth to send post requests to this URL. Hence, I keep getting a 401 unauthorized error whenever I do a POST request.
I do not see any way to add these authorization details anywhere in my slack app configurations. How do I make a request to this URL? Is there an alternative way to add the authorization header to this POST request?
