Can we extract this logic into some common function?

[soleksy-splunk]

I thought about it but in the end not sure if it make sense.
As if we make it common, then it it needs to be something like

const waitForRow = async (rowName: string | RegExp) => {
    return screen.findByRole('row', { name: rowName });
};

which is one liner that seems to not improve visibility of the code 🤷 wdyt?

[rohanm-crest]

ohh sorry, commented on different line.
I mean to say, if we can extract logic for this regexp smtg like this:

const rowNameRegex = (interval: number) => new RegExp(`${inputName}${intervalBase}${interval}`, 'i');

NIT: it is declared at only two place, so we can skip it as well, whatever you choose works for me.

that one make sense, but modified a bit differently, let me know wdyt.
