How do I activate My Pro account on my Mac Pro laptop?

I installed Wappler on my Windows 10 laptop and was using it when I paid for my Pro account.

I had downloaded Wappler on my Mac Pro, running to test the trial on Mac

I have downloaded the 1.6.2 for the Mac in the past few minutes.

I’m going to overwrite/update 1.6.1 on my Mac – but how do I activate it on my Mac?

I don’t find prominently displayed instructions

Thanks for Help!
