is app indexing is necessary for instant app to show in google search

Question

I have developed an instant app & published it into the play store, also has a website associated with the Instant App. tested the app link with the testing tool from here .

The app is opened after clicking the link from other apps (gmail, hangouts), But clicking on my website from a google search is opening as a webpage instead of instant apps. Is there anything I have to do in order to redirect a web page to the app from google search.

I had published my instant app in play store. when i click the link from gmail it opens as instant app in some devices (Samsung s6 note ,moto g4 plus)

On some devices its not opening as instant app but buzzfeed.com/tasty opens as instant app. (one plus 3 & one plus 5).

my digital asset link is https://abdcoop.mybuzztm.com/.well-known/assetlinks.json

Anyone able to suggest what i am missing?

It is not necessary to use the App Indexing API. As long as you set up App Links, that's enough. Unfortunately, it can take several weeks for the change to show up in Google search results. We do consider that a problem and are working on a way to speed it up.
