Doesn't it look just like a paint scraper!

That's basicaly what it is. But with a few of differences the blade needs
to be quite stiff, most paint/paper scrapers are too flexible. It needs to
be fairly broad, say around 3" so the force to ping the seal is applied of
a reasonable area and won't cause the scraper to dig into the soft
plastic. The edge needs to be fine but not sharp to get into the tiny gap
without cutting the plastic if slightly misaligned.

OK that makes sense.

I do have a fairly stiff scraper (might not be officially a scraper, but
looks like one) - I'll try that first.

I have take out double glazing beads using two fairly used scrapers.
The first one is tapped into the bead to window frame joint
(perpendicular to window). Tap the second one along side the first.
Then use a screw driver between the two scrapers to force them apart
and start to remove the bead. Once the bead starts to move it is then
easy to remove completely. Doing it this way does not damage the
beading. The secret is to use well worn scrapers say about 50mm wide.
If you haven't got a worn scraper file down a scraper to give it a
tapered leading edge.
