WebGl outputting a 'Build' folder instead of a 'Release' folder

Hi, I am a begginer in WebGL and I am running into a problem where my game successfully outputs and the test works in browser, however in the output folder there is a ‘Build’ folder instead of a ‘Release’ folder.

The TemplateData and index.html files appear to be fine, it’s just not giving me the Release folder.

Any help is appreciated

Release folder is used by versions lower than 5.6 …
… from 5.6 onwards new construction is used (with Build folder and new templates)
