Hello and welcome to BW forums.
Sorry you didn't get support yet, it's a busy time of year and many of our community take a little time off to enjoy celebrations with their families.
The dummy can certainly become a prop. Tracy's advice on dummy use was to use it for LO to fulfil their sucking reflex just prior to sleep, to watch for when the rapid hard sucking reduced to slower, weaker sucking and then remove it so taht sleep came without dummy use.
It is not advised to drop the dummy cold turkey before 6 months old (SIDS guidance) if LO is already dependent on it for sleep so my advice at this point would be to continue as you are for another month or so and then wean the dummy if you want to.
Some people like to keep the dummy and teach LO how to find and replug themselves which you might prefer, or else you can use shush/pat to drop the dummy in a month or so.
It might also be that she is in a very light sleep in those early hours, this could be routine based and a tweak in your overall routine might actually help her to sleep more soundly and reduce the need for the re-plugging in the early hours. If you would like to post your EASY times we could have a look for you and see if there are any changes we might suggest. She is approaching the time when most babies drop a nap so this could be on the cards now.
Hope this helps.
