Method:
First i visited this website which is a great resource for ciphers and decoding challenges. https://gchq.github.io/CyberChef/
Then i pasted in the string and used the magic symbol to check what cyber chef recommends.
This converted from base 64.
Then i clicked it again to convert from base 32 which was recommended.
This then outputted the flag.
flag = leveleffect{two_to_the_five_two_to_the_six}
A very easy one using cyber chef and a great resource to use.
