There is no need to use the picker and the name field:

If you hoover with the cursor over the ⓘ of the flow card, an additional info will be displayed:

So if you want to create a new timer name, first you have type in the name. After saving the flow, the name of the timer can be chosen by the picker field and the timer name in the name field can be deleted. Using the picker avoids typos.
