I am new to openstreetmaps. I just wanted to know whether it had any integration with gnome-maps. I was not able to add new locations using gnome-maps even after I set up OSM account with gnome-maps.

Hi, any screenshots would help (you can upload them on and paste links here).
I also think gnome-maps has to have its own help/support website.
PS: It’s OpenStreetMap, not openstreetmaps.

Please tell us exactly step by step what you have tried so far, and why it has failed then.

Otherwise we cannot reproduce any error or give you better hints.
