Replace fixed plastic pane with glass

Hello,
I recently moved into an apartment and have a fixed window element in the conservatory, which is currently filled with a plastic pane.
I would like to replace this with a glass pane. For this, I would first need to remove the plastic element.

Here is my problem. Since I do not know how the lock works, I was unable to remove the pane.
Therefore, my question is for tips on how I can replace the pane or how I can open the paneling.
I have already tried to pry off the side strips, but they seem to extend behind the plastic pane and do not appear to be normal glazing beads that are simply placed from the front.

I would be grateful for tips as well as possibly videos or search terms that I can look up. Unfortunately, I do not know the manufacturer of the windows, the type of the windows, or the name of the lock either.

Thanks in advance

Sorry I was probably mistaken after all and these are just normal glass strips that I can simply remove

These are actually the same glass strips.

Since no links are allowed here, just google "remove glass strips." Then you will find suitable videos and the right tools.

Addendum: I was probably too slow...

Thank you. Unfortunately, a problem has still occurred. Unlike most other videos, I apparently have these blue locks. Does anyone possibly know how to remove the glass trims? Do I have to pay special attention to these locks?
Unfortunately, I also have to use a lot of force to remove the glass trims.
