how do i upload projects to my cloud from unity hub

(earlier…i had option for on disk and in cloud, but now it seems to be gone)

There is an option in unity editor on the top right hand side you should see ‘collab’ and cloud icon buttons.

You can do this simply in the upper-right menu, there is a button. However, I think you can migrate your project to any other cloud solution. You can read useful information here learn more about cloud migration

Can you also do this via webbrowser? im using unity in a seperated offline enviroment and want to upload the stuff in the cloud using a network-connected interface which cant use unity-editor itself.
