I'm glad to hear you were able to solve the first issue.
To confirm, you are trying to use the legacy Video Milestone implementation for Analytics as described in the documentation here correct? If so, this has been replaced by the Video Heartbeat model which I would encourage you to look into.
I'm not sure I fully understand your question, but if you're looking for which event needs to be used for your milestone implementation, it looks like you can use any event you'd like. You'd want to make sure your report suite doesn't already have a conflict with using the event, but the milestones aren't tied to a specific event as far as I can tell.
I believe direct call rule needs to be triggered from developer end but same thing I am able to do it via DTM and have shared the complete code with you. Could you please suggest where exactly s.t or s.tl call needs to be mapped.
You are absolutely correct from my code which I have written in DTM I am able to log events in console but not seeing Adobe call for those events.
Could you please help how Adobe call for video events can be triggered?
Can you try and attach a bigger version of the screenshot? When I try to see what is being displayed in the console, everything appears to be blurry and unreadable.
From what I can see, it looks like your functions are running since you are getting the console messages you've programed. Are you just not seeing an Analytics beacon being fired? If so, where are you calling the s.t() or s.tl() call? It looks like you are setting a lot of variables and sending messages to the console, but I don't see any s.t or s.tl calls.
If it were me, I'll add direct call rules to the functions. Then within the DTM user interface, you can set the variables and select which type of beacons to fire.
