How do I activate my ORANGE bundle?

Excuse me, could you please provide me with a step-by-step guide on how to activate my ORANGE bundle? I've recently purchased it but I'm unsure of the process to activate it. Would I need to dial a specific number, or can I do it through the ORANGE app on my phone? Additionally, is there a specific time frame within which I should activate it to avoid any loss of benefits? I'd really appreciate your help with this, thank you.
