The title of this issue is (slightly) misleading (and one could argue also incomplete).

Based on the whats-new post: what was added to SNS filtering:

• $or operator
• suffix matching
• case insensitive matching ("equals-ignore-case")

The title of this issue also mentions $and but that does not exist (+ the two other new additions are not included).

Note: that this also requires changes in moto for which I created getmoto/moto#7386

@bram-tv that’s fair, not sure how I misread that - any suggestions for a better title? Other than omitting the nonexistent operator

edit: updated title and description
