Scala String indexOf Character from the Right Side

What is an idiomatic way to find the index of a Char in a scala String starting from the right side of the String (instead of starting from the left side using indexOf)?

Examples:

def indexOfFromRight(s: String, c: Char): Int = ???

assert(indexOfFromRight("iii", 'i') == 2)

assert(indexOfFromRight("abbabb", 'a') == 3)

assert(indexOfFromRight("foobar", 'x') == -1)

Thank you in advance for your consideration and response.

As commented: the lastIndexOf method of String accomplishes the right side find.
