I would advise using upvc superglue to stick the trim back as it is an internal trim, you can then use decorators caulk to seal between the trim and the wall as this can then be painted when decorating.

You will find that using silicone it doesn't adhere very well to plaster.
You might find that a water based adhesive is better such as Gorilla or Tec as theese will not stain the uPVC trim.

We find the best and easiest way is to ensure a good clean surface to both sides (trim and wall) and the use a good quality super glue with activator helps and then seal up with correct colour silicone to cover any gaps .

To remix trim you need to 1st remove old silicone and dirt by cleaning it with a cloth. Then get a good quality silicone and gun if you don’t have one from any diy store . Then cut the tip of about 5 mm at an angle this will help you get a clean sharp line around trim edges . Apply silicone by gently keeping pressure on the gun trigger go all round trim edges you wish to seal . Then wipe the end of your finger with a damp cloth and wipe it along in one straight motion. When you teach the end of trim wipe finger again and repeat until all sealed. To stick trim just apply silicone to back if trim either in raised dots or a wavy line then stick to window or what surface you wish to stick to
