Let’s take the Rhine Which goes from Switzerland to Netherlands. When and how did people start agreeing on giving-it the same name ? What about the alps going from southern France to Austria ? When did people agreed that it was the same mountain range ? And obviously what about the Gulf of Mexico ?
Typically starts by wiping out the people that had other names for it.
Consider the Thames river. Which one? Depends on how you read it out loud.
The “Temz” runs through London while the “Thayms” runs through somewhere in Connecticut.
They didn’t, a lot of shared places, or land features have different names in differsnt languages and different places. Agreements happen when something either didn’t have a name before, or when the name came from the past.
I find those funny, which just have the same word in another language for their name, like the River Avon or the Sahara Desert or even Torpenhow Hill which is “Hill Hill Hill Hill” in different languages.

‘Loch Lochy’ in Scotland.
There also are multiple rivers with danu root, that also means river: danube, donets, don. People aren’t exceptionally good at naming in general, so “hill” hill and “river” river. 😄
Also town town, mountain mountain, and my favourite, river hill mountain town town.

River Avon in the UK derives from Celtic word for river (Avon).

For the most part, whomever the mapmakers happened to ask got to decide. Once it’s on an official map, it’s just gonna drown out any other opinions.
Several places in Norway have names that are spelled “wrong” according to locals, but changing it requires herculean efforts of bureaucracy.
I recognize that you are asking about European place named but how humans named things in North America might give some insight. A really great book on how places got their names in the US is Names on the Land: a historical account of place-naming in the United States by George R. Stewart (ISBN 978-1-59017-273-5).
This video talks about a US agency that’s responsible for doing exactly that
