Problems in Setting I/O events with local AEMaaCS instance

Hello.

Note - Moving this question to I/O events section. 

We are trying to set up AEMaaCS with Adobe IO runtime actions through IO events.

after setting up Adobe I/O Events IMS Configuration on local AEMaaCS, we get healthy configuration as mentioned here - AEM (6.4.x and above) Adobe IMS configuration , but when we navigate to our IO workspace and click "Add to Project" -> "Event", we don't see our local instance name to select - This step `AEM Link Externalizer` Configuration (adobe.io) . 

can someone please help, we are stuck here and not able to move ahead.

Thank you.
