Convert a paragraph block to a number counter

Add a paragraph block, write a number inside it, and assign it the “counter” class. That’s it, you can also change the style of the paragraph to your liking.

For example, the above pattern is made by the following blocks. A row block in which there are four groups and in each group there is an image block and a paragraph with the “counter” class.
