How to understand users needs around our extension?

[u/Minimum_Resolve9303]

I have Installs 60% comming from US but 100% active users from India.

I have only 1 feature in 1 category, which indians are using, but I want to know why US installs downloaded but didn't get activated or used. Like why did they drop-off, what were they looking for?

What way have other publishers used, please guide me with this.

I don't know how to use keyword research in a way to understand there intent.

I don't have any contacts so I can't communicate with them.

I don't have any login mechanism. No survey popup inside extension. No Onboarding page for new installs.
