***Implied in that it the power to approve leaving as well.***

No it isn’t. You don’t need permission to leave a group you voluntarily joined even if it took approval of that group to get in. I can quit my job any time I please even though my employer had to “admit” me. Unless there is some provision in the contract that says I owe X amount of days or must provide X days of notice. And there isn’t in the Constitution.

The fact remains that secession is not denied to the states and is thus protected by the 10th Amendment.
