how to complete this phrase?

hello everyone,

I'm not sure how to go about completing this phrase correctly,and since I can't find any similar ones on the internet I thought I'd ask here.
In english, it is "She knows very well that she must not send messages via (message system),but she just wants to ask how (specific event) was."

In japanese,I've got parts of the phrases, but I don't know how to put the "knows very well" and "just wants to ask" parts. For the "knows.." part,would you have to use something like 「のこと」or something more like『と知って』?Bit lost.
Thanks to any constructive help:)

She knows very well that [she must not send messages via (message system)], but

Either of the following for the first half
- Kanojo wa [(message system) wo tuujite messeeji wo okutte wa ikenai] to yoku wakatte imasu ga,
- Kanojo wa [(message system) wo tuujite messeeji wo okutte wa ikenai] koto wo yoku wakatte imasu ga,

she just wants to ask how (specific event) was.

- kanojo wa (specific event) ga dou datta ka shiritai dake desu.
