In Singaporean English, what does the phrase 'Ok, Ken' mean?

I was in a training session today with a Singaporean trainer (lah!) and he kept using the phrase:

"Ok, Ken"

I checked the meeting attendees for a ‘Ken’ – but there was definitely no ‘Ken’ in the room.

He kept repeating it, also using the phrase:

"Alright, Ken".

Eventually I inferred that he must be using a contracted version of:

"Ok, I am confident that you can do this."

But I wasn’t sure.

I didn’t know whether this was a Singaporean English expression (lah!) or if he was just taking a Mandarin phrase in his head, and translating it directly into English.

My question is: In Singaporean English, what does the phrase ‘Ok, Ken’ mean?

The context was an IT Training course. For example:

Trainer: Here is how to install Azure Migration assistant and perform a Cloud Migration.

[Performs 25 steps]

Trainer: So that is how you use Azure Migration assistant. Ok can.

Or another example

Attendee: [Complicated question]

Trainer: It’s easy!

[Talks through 15 steps]

Trainer: So that is how you do it. Alright can.
