don't need anything, simply chain the replacements together:

val value = Base64.getEncoder().encodeToString(bytes)
                          .replace(...)
                          .replace(...)

i just did this:

val value = Base64.getEncoder().encodeToString(bytes).run {
		replace("+", "-").replace("/", "_").replace("=", "")
	}

¯\_(ツ)_/¯

same thing, ahah

😂 1

i’ll just rmeove the run then
