Means you want to target your users. You can use location or maps component for that and put latitude and longitude for that specific region.

And show what you tried , show blocks and what result you got

an extension does not need loads of blocks… only one is perfectly fine if that can solve a problem…
but please start a new thread, add a screenshot of the blocks and a small description of its functionality…
thank you!
