How to convert particle system to actual keyframes?

Noob question:

I have used a particle system to create bubbles that float upwards in my scene.
Now im looking for a way to turn all the bubbles to its own mesh with its own keyframes, so I can manually tune the bubbles if necessary… I also want to keyframe some opacity values manualyy for some bubbles…

Is this possible?

there seems to be no internal solution,
probably it will be possible with GeometryNodes at some point,
until then it seems to work very well with this
before you apply this you have to bake the particle system,
then select what you need and then the particlesystem to it, then in the objecktproperty you find as described

Thank you for your reply, this should help me out!
