Se as 'it', le and les as direct objects
I know that 'se' can be reflexive ('me lavo' or 'te vistes'). It can be used to say that people are doing something to or with one another (such as 'se pelearon' or 'se besaron'), but I'm confused as to when it doesn't refer to people.
Such as this example from a popcorn bag which I think 'se' might refer to the bag and not the person handling it: "Manéjese con cuidado; la bolsa y el aceite ¡están muy calientes!"
To me this sentence reads: "Handle to you it with caution/care; the bag and the oil are very hot!" Does it mean this? And if so, why? If it doesn't, what is an easy way to remember the use of 'se' here? When does say mean 'it' or 'itself' and how can I remember that usage?
I also read that le and les can be used as direct objects which means that they would function something like los/las/lo/la, but how would that work?
I hope this question make sense and what I see actually exists haha

Se has many uses, but this one means yourself, it is pronominal
"Manéjese con cuidado; la bolsa y el aceite ¡están muy calientes!" Manéjese here is a Usted command.
Manage yourself with care- the bag and the oil are very hot.
An example not referring to a person follows:
Se prohibe fumar- smoking prohibits itself (some would argue with thinking of it this way, because this really is passive/impersonal se)= smoking is prohibited
Le when used as a direct object in place of lo is leísmo:
https://en.wikipedia.org/wiki/Leísmo
Leísmo is not as common with les replacing los. It is not ever used for la or las.
Le and les are normal indirect objects. For masculine or feminine indirect objects.
I see the phrase as "You should handle with care because the oil...." "Manejar" is transitive and it needs an object. The object in this case is the bag, so it could be written, "Maneje con cuidado la bolsa porque el aceite....". But, that's too much of a mouthful.
