Which plug should I use on aerated concrete? (leca)

[Elnovis]

I am planning to screw Schneider Exxact wall sockets and switches onto a lightweight concrete wall (leca). There are 4 screws on each. Which plug should I use to ensure that the items are securely fastened?

Actually, any "Universalplugg".

For example;

on a lightweight concrete wall (leca).

When drilling, it should go as slowly as possible with no impact, leca tends to crumble and then the hole becomes larger.
