Issue retrieving user information (name and email) from the membership service with an LTI 2.0 tool provider

Download ngrok if you don't have it from https://ngrok.com/ . Run ngrok (eg. ./ngrok http 80 --region=au). Change your wwwroot to use the https URL. Add $CFG->sslproxy = true to your config.php. Visit 'Site administration' > 'Plugins' > 'Activity modules' > 'External tool' > 'Manage tools'. Paste 'https://lti.tools/test/tp.php' into the Add Tool input. Click 'Add'. In the tool registration settings, click 'Registration'. Select all 'Enabled capabilities'. Select all 'Tool services'. Click 'Register tool'. Click 'Yes' to accept the request for data. Visit a course. Add an 'External tool' activity. Select the tool you added in the 'Preconfigured tool' drop-down. Click 'Save and return to course'. Click on the activity you added. In the tool provider page, click 'Membership'. Click 'Read'. In the response contained in the modal, ensure that the attributes userId, sourcedId, name, givenName, familyName and email are returned for each course participant. It may be helpful to copy and paste the response body into text editor to make reading easier.
