Automatically fill in missing numbers from a list, adding a cell for each missing number

Let's say I have an excel Sheet where in the first column is:
1
3
4
7
10

How can I quickly fill up this list with the missing ascending whole numbers such that it reads? An alternative way to put it is that I want to fill in the list of ascending numbers, adding a row for each missing number

1
2
3
4
5
6
7
8
9
10

Many thanks.

or, since you have O365:

=SEQUENCE(MAX(A1:A5),,MIN(A1:A5))

if the sequence always starts with 1 (even if it is missing from the list):

=SEQUENCE(MAX(A1:A5))
