How to understand these two sentences?

Hi,

Could someone tell me how should I understand the underlined parts of the following two sentences? Thanks!

Sentence A
You just got to make it look like it was their idea like they’re the ones that thought of it.

Sentence B
They need to feel like they’re the great emancipators like it was theirs to give in the first place.

Since what I do not quite follow is that the unerlined parts may be the standard way English native speakers speak, but If I were him, I would use my own way cuz I'm not quite familiar with this usage. So if you could explain the underlined parts in the above contexts, that would be great. Examples, if you have, will be helpful to me.

PS: According to what the translation shows, I guess, the first underlined part means, make it look like they realize this point themselves, and the second one refers to, like they put themselves in the first place every time.

Thanks!
