Sleeping in a pack and play - HELP

So my daughter is a little over 3 months old and 9kg. A large baby.

The weight limit for her bassinet is 9kg, so we have to find something for her to sleep in ASAP.

A crib doesn’t fit in our room but we want her with us until at least 6 months as per SIDS recommendations.

SO, Is a pack and play/portacot a safe place to sleep baby until this point?

We absolutely will not have her in our bed. Anyone else have this issue? 😞
