The delete option is not available on Connect, but you can always edit your post by clicking the 3 little dots, which are located on the left side of your publication and then choose “Edit message”. As well, you can have a look at this post: Edit your post - Why and How To.
When you have a question, you can start a new post or search if there is something similar to what you are asking already on Connect. I’ve changed a bit the title of your post to a more descriptive one.
I will merge both of your post related to the same topic.
