Are these a 1 time use until you level or just a long rest type of "spell? Cause I'm curious about the invocation that adds 2 spells to your spellbook. Could you do that daily? Daily use allow you to change to 2 spells, or is it a 1 time use?
Invocations are essentially a list of optional class features. They do exactly what they state. Think of them more as being "equipped" than cast.
For example,
Agonizing Blast adds a modifier to your eldritch blast damage.
Armor of Shadows lets you cast mage armor for free as an action an unlimited number of times.
Bewitching Whispers lets you cast Compulsion once per long rest for free.
Book of Ancient Secrets gives you a book with two spells, which you can then add to. This happens once, and if you swap it out at a later level, you lose the book and the spells.
So the answer you're looking for is, "No, you choose the two 1st level spells when you take the invocation and must inscribe any additional spells you find as normal."
