How to use QQ pet's star card after receiving it?

Compared with the old version, the new version of QQ lacks two ways for pets to consume constellation cards. The original "open constellation diagram" and "card magic disk" are gone now, so now we can only choose:

1. Go to Sharpa Coast-Super Amusement Park and use the constellation card to participate in the game to win the treasure, so as to get the reward;

2. In Penguin Town-Wing Prophet receives the task of love, and the task of love will randomly receive the task of which card is needed.

I hope I can help you!
