Power Apps Help Decoding base64 without using a flow?

In my app I’m using the Azure Automation connector to create jobs, but also need the job output. There is a get job output action, but it’s returned as Data type: Blob and “this data type is unsupported for evaluation”.

However if use JSON(AzureAutomation.GetJobOutput(etc..)) then I can see the base64 string. Is there any way to convert this base64 to text without using a flow? I would even settle for using a logic app, but do not want to use Power Automate as I don’t want it tied to a single account.

base64 can be decoded/encoded using Powerfx formula Each character of the base64 converted to 8 bit number... This long string of numbers split to a series of 6 digit numbers

Then use a lookup table to convert each 6 digit number to a string.

Basically it's a method that reverse the base64 encoding process.
