Need help replacing the probe/proximity sensor

I received my new sensor today, but the video support told me to follow, does me no good. The plastic piece it attaches to , there is no way to mount it. The old one had glue on it like it was attached in production, this one does not. Why not send me both with it attached.

Same problem here. I just mailed support.
I got only the probe from Snapmaker. Thus I have to detach the broken one from the air duct support and reattach the new one.
But I do not want to force it and break the duct.
Also I have no idea of which glue is used. I suppose it has to be something heat resistant…

How do you solved it?
Which kind of glue is used to fix the probe?
What the best way to detach it from the support is?

Please, help is welcome
