Vscode: [folding] show folding actions at the end of folding range as well

[WhatFreshHellIsThis]

This is for C# but may affect others I'm not sure:
Having a large complex code block and wanting to fold it requires always scrolling to the top of the region to collapse it. There should be an identical folding icon that allows to fold from the bottom of the region.

Thanks bot, I don't see this anywhere in those possible duplicates.

@WhatFreshHellIsThis you might find The Folding Stuff useful. It's a small extension I created that surfaces folding commands on the context menu.
