This is a snippet to have anchor view function not trigger wallet confirmation
async readOnly(instruction: TransactionInstruction, instructionName: string): Promise<{ value: any }> {
// Filter through your IDL to get the actual read instruction schema and return type
const ixx = IDL.instructions.find((i) => i.name == instructionName);
// This checks if the instruction contains Mutable account, if it does, then it isn't a read only instruction
const isMut = ixx && [...ixx.accounts].find((a: any) => a.isMut);
const returnType = ixx && (ixx as any).returns;
if (isMut || !returnType) return { value: null }; // basically return null value if ix is mutable or it doesn't contain a return type
