Channel Divinity uses and short rests

I want to make sure I’m interpreting this correctly.

At level 2, a cleric has 2 uses of Channel Divinity. The feature says you regain 1 use after a short rest and all uses after a long rest.

So my question is:

Is it correct that the cleric effectively has a maximum “pool” of 2 uses at any given time, and can only regain 1 per short rest (up to that maximum)?

If that’s the case, then even with multiple short rests in a day (for example, 3 short rests), the total number of Channel Divinity uses in that day would be limited (e.g., you don’t just add +1 per short rest indefinitely).

Or instead, is the correct interpretation that you can effectively use it multiple times across the day (e.g., 2 initial uses + 1 per short rest, if you spend them all before each rest)?

Thanks in advance for clarifying!

2 uses max after each long rest WHEN I TAKE A SHORT REST I CAN RECOVER 1

the channels remain 2 max of use then they discharge until I do 1 short rest and recover 1 or do a long rest and recover 2

if in a day

before I use 2 -after rest and recovery 1 -
after use 1 - after rest and recovery 1
 after reuse 1
I can use even 4 in a day
