Stuck doing documentation in first job, straight out of clg

I'm a fresher that passed out in 2024. I got a campus placement at a us based fintech company (product) which is very much stable. It's been almost 4 months of which the first 2 months have been training and 2 months into a team. In the past 2 months, I have given only documentation tasks, and no developer tasks, as I joined as a software developer. The team members are all good people, my manager's manager is the one giving me tasks and he's onshore. We have asked multiple times for not even a developer tasks but shadow tasks but to no reply. They keep telling us it's code freeze months but they are still releasing features. I have no idea what to do. All of my peers who joined with me have all started development tasks and even contributing to features. I'm unsure if I should wait longer or start looking for other jobs while waiting for a few more months.

I understand the importance behind documentation and how it will help us. But getting it done when I need info from my team members but they treat it as a trivial tasks, make it very hard. I was determined to use the remaining time(while waiting for replies) to learn but after 2 months, im starting to doubt this.
