Hosting address appears in Google's results, instead of Domain address

I’ve look around to find something on that subject but I didn’t found anything applying to this.

I host my wordpress on a web hosting service, so it has an url like this https://webfab.cluster1.easy-hebergement.net/gototogo-v0/.

And my issue is that this is the address that appears in google results and not the domain address https://gototogo.fr/.

I’m quite desperate about this because I still haven’t the faintest clue of how to do this… If you have any pointers or advices, they’ll be very welcome!
