Is Mamata Banerjee trying to project herself as the next PM contender in 2024 general elections?

Mamata Banerjee (the current Chief Minister of West Bengal) is organising so many "multi party meetings" on various issues (such as the current issue of upcoming presidential elections) to "unite the opposition"; most prominently in last couple of years. Many major political parties seem to be with her including INC, SP, BSP, NCP etc.

Her language seems extremely harsh like she just can't stand the current Union Government.

Question

• Is she trying to project herself as the next PM contender?
• What is the possibility of her uniting the opposition against the ruling party BJP for the general elections of 2024?
