How to use javascript to determine whether kakao talk app is installed

When I run the javascript web sdk on the mobile ios device and safari browser,message kakao link cannot be opened.
so I need to judge whether kakao talk is installed

Hi~
I will also send this question to our technical team and check it as before
i apologize in advance for the delay in answering, but we are using our time to find a better direction.

thanks

We use the Custom URL Scheme method to keep UX good when Kakao is installed in IOS.

However, in order to solve this issue, the SDK must be updated to use Universal Link, which adversely affects UX.

So we are carefully watching this special situation where Kakao was not installed first, and we are continuing to review it internally.

Therefore, there is no update plan for this issue yet.
i’m sorry I didn’t tell you the good news

I got it, thanks
