Sync Channel permissions with parent

[eyagovbusiness]

Hello, Since Discord support synchronizing a new channel with the parent category permissions as in the picture (Apologies for not being in English).

I would like to know how I can declare I want a channel to be synchronized with the parent when calling CreateChannelAsync() method. With discord is enough to add new channel to category, leaving it not private and not specify any permissions, then the new created channel is by default sync with the parent category.
I tried not specifying any DiscordOverriteBuilders and setting the parent category... but it does not work :(

Thanks

"leaving it not private and not specify any permissions, then the new created channel is by default sync with the parent category."
This is actually working, I did not notice I had a permission overwrite set by mistake....
Apologies but I am not allowed to delete the discussion.
