Recently purchased a used road bike, has a tubeless setup and I noticed these small white beads/droplets on the rear, assuming this is sealant. They appear at the tire seam a few mm above the rim line. The tires are holding air just fine, but these beads reappear after I wipe them off.
Is the rim not sealing properly? Or need a new tire? Thanks in advance.

Just ride them. These are common and will seal. If they reappear for multiple days, consider adding more sealant
to replace the amount you lost.
Looks normal, you should ask seller what sealant he used and buy some to have around.
If it gives you headaches, you can always run a tube. Tubeless really shines offroad at lower pressures.
That’s normal, just go ride it to make sure the sealant spreads evenly.
I have had WTB tyres which did this every so often when I ran the pressure high, was carrying more load bike packing or when it was really cold / wet outside (picture attached)

Normal for some brands. None of my my panaracer or specialized tires do this… but all of my wtb tires in the lightweight casing options do this.
All normal. See that line parallel to the rim outer diameter on the tire? That is your best indicator of a proper tape job and a properly seated tire, which is the most important thing in tubeless, assuming you have tape over the spoke holes.
