Get entities and their text. Extracts the text from ctx.msg.text or ctx.msg.caption. Returns an empty array if one of ctx.msg, ctx.msg.text or ctx.msg.entities is undefined.

You can filter specific entity types by passing the types parameter. Example:

ctx.entities() // Returns all entity types
ctx.entities('url') // Returns only url entities
ctx.enttities(['url', 'email']) // Returns url and email entities
